(VirtualBox web service sources and SOAP mappers; (smart Qt-based C++ wrapper classes for COM interfaces (Main API TypeLib block for the WiX installer) (<result> extraction for the %Rhrc format specifier) Welcome to the <
b>VirtualBox Main API documentation</
b>. This documentation
describes the so-called <
i>VirtualBox Main API</
i> which comprises all public
COM interfaces and components provided by the VirtualBox server and by the
VirtualBox client library.
VirtualBox employs a client-server design, meaning that whenever any part of
VirtualBox is running -- be it the Qt GUI, the VBoxManage command-line
interface or any virtual machine --, a dedicated server process named
VBoxSVC runs in the background. This allows multiple processes working with
VirtualBox to cooperate without conflicts. These processes communicate to each
other using inter-process communication facilities provided by the COM
implementation of the host computer.
On Windows platforms, the VirtualBox Main API uses Microsoft COM, a native COM
implementation. On all other platforms, Mozilla XPCOM, an open-source COM
All the parts that a typical VirtualBox user interacts with (the Qt GUI
and the VBoxManage command-line interface) are technically
front-ends to the Main API and only use the interfaces that are documented
in this Main API documentation. This ensures that, with any given release
version of VirtualBox, all capabilities of the product that could be useful
to an external client program are always exposed by way of this API.
The VirtualBox Main API (also called the <
i>VirtualBox COM library</
i>)
contains two public component classes:
implement IVirtualBox and ISession interfaces respectively. These two classes
are of supreme importance and will be needed in order for any front-end
program to do anything useful. It is recommended to read the documentation of
the mentioned interfaces first.
there can be only one object of this class on the local machine at any given
time. This object is a parent of many other objects in the VirtualBox COM
library and lives in the VBoxSVC process. In fact, when you create an instance
process is already running, starts it if not, and returns you a reference to
the <
tt>VirtualBox</
tt> object created in this process. When the last reference
to this object is released, the VBoxSVC process ends (with a 5 second delay to
protect from too frequent restarts).
as many <
tt>Session</
tt> objects as you need but all of them will live in a
process which issues the object instantiation call. <
tt>Session</
tt> objects
represent virtual machine sessions which are used to configure virtual
machines and control their execution.

descGroup id="VirtualBox_COM_result_codes" title="VirtualBox COM result codes">
This section describes all VirtualBox-specific COM result codes that may
be returned by methods of VirtualBox COM interfaces in addition to
standard COM result codes.
Note that along with the result code, every VirtualBox method returns
extended error information through the IVirtualBoxErrorInfo interface on
failure. This interface is a preferred way to present the error to the end
user because it contains a human readable description of the error. Raw
result codes, both standard and described in this section, are intended to
be used by programs to analyze the reason of a failure and select an
appropriate course of action without involving the end user (for example,
retry the operation later or make a different call).
The standard COM result codes that may originate from our methods include:
<
tr><
td>E_INVALIDARG</
td>
Returned when the value of the method's argument is not within the range
of valid values. This should not be confused with situations when the
value is within the range but simply doesn't suit the current object
state and there is a possibility that it will be accepted later (in such
cases VirtualBox-specific codes are returned, for example,
<
link to="VBOX_E_OBJECT_NOT_FOUND"/>).
Returned if a memory pointer for the output argument is invalid (for
example, @c null). When pointers representing input arguments (such
as strings) are invalid, E_INVALIDARG is returned.
<
tr><
td>E_ACCESSDENIED</
td>
Returned when the called object is not ready. Since the lifetime of a
public COM object cannot be fully controlled by the implementation,
VirtualBox maintains the readiness state for all objects it creates and
returns this code in response to any method call on the object that was
deactivated by VirtualBox and is not functioning any more.
<
tr><
td>E_OUTOFMEMORY</
td>
Returned when a memory allocation operation fails.

uuid="ec6c6a9e-113d-4ff4-b44f-0b69f21c97fe" Virtual machine execution state.
This enumeration represents possible values of the <
link to="IMachine::state"/> attribute.
Below is the basic virtual machine state diagram. It shows how the state
changes during virtual machine execution. The text in square braces shows
a method of the IConsole interface that performs the given state
+---------[powerDown()] <- Stuck <--[failure]-+
+-> PoweredOff --+-->[powerUp()]--> Starting --+ | +-----[resume()]-----+
| Aborted -----+ +--> Running --[pause()]--> Paused
| Saved -----------[powerUp()]--> Restoring -+ | | | |
| | +-----------------------------------------+-|-------------------+ +
| | +-- Saving <--------[takeSnapshot()]<-------+---------------------+
| +-------- Saving <--------[saveState()]<----------+---------------------+
+-------------- Stopping -------[powerDown()]<----------+---------------------+
Note that states to the right from PoweredOff, Aborted and Saved in the
above diagram are called <
i>online VM states</
i>. These states
represent the virtual machine which is being executed in a dedicated
process (usually with a GUI window attached to it where you can see the
activity of the virtual machine and interact with it). There are two
special pseudo-states, FirstOnline and LastOnline, that can be used in
relational expressions to detect if the given machine state is online or
...the machine is being executed...
When the virtual machine is in one of the online VM states (that is, being
executed), only a few machine settings can be modified. Methods working
with such settings contain an explicit note about that. An attempt to
change any other setting or perform a modifying operation during this time
will result in the @c VBOX_E_INVALID_VM_STATE error.
All online states except Running, Paused and Stuck are transitional: they
represent temporary conditions of the virtual machine that will last as
long as the operation that initiated such a condition.
The Stuck state is a special case. It means that execution of the machine
has reached the "Guru Meditation" condition. This condition indicates an
internal VMM (virtual machine manager) failure which may happen as a
result of either an unhandled low-level virtual hardware exception or one
of the recompiler exceptions (such as the <
i>too-many-traps</
i>
Note also that any online VM state may transit to the Aborted state. This
happens if the process that is executing the virtual machine terminates
unexpectedly (for example, crashes). Other than that, the Aborted state is
equivalent to PoweredOff.
There are also a few additional state diagrams that do not deal with
virtual machine execution and therefore are shown separately. The states
shown on these diagrams are called <
i>offline VM states</
i> (this includes
PoweredOff, Aborted and Saved too).
The first diagram shows what happens when a lengthy setup operation is
being executed (such as <
link to="IMachine::attachDevice"/>).
+----------------------------------(same state as before the call)------+
|-> Aborted -----+-->[lengthy VM configuration call] --> SettingUp -----+
The next two diagrams demonstrate the process of taking a snapshot of a
powered off virtual machine, restoring the state to that as of a snapshot
or deleting a snapshot, respectively.
+----------------------------------(same state as before the call)------+
| +-->[takeSnapshot()] -------------------> Saving ------+
| Aborted -----+-->[restoreSnapshot() ]-------> RestoringSnapshot -+
| | [deleteSnapshot() ]-------> DeletingSnapshot --+
+---(Saved if restored from an online snapshot, PoweredOff otherwise)---+
Note that the Saving state is present in both the offline state group and
online state group. Currently, the only way to determine what group is
assumed in a particular case is to remember the previous machine state: if
it was Running or Paused, then Saving is an online state, otherwise it is
an offline state. This inconsistency may be removed in one of the future
versions of VirtualBox by adding a new state.
For whoever decides to touch this enum: In order to keep the
comparisons involving FirstOnline and LastOnline pseudo-states valid,
the numeric values of these states must be correspondingly updated if
needed: for any online VM state, the condition
<
tt>FirstOnline <= state <= LastOnline</
tt> must be
@c true. The same relates to transient states for which
the condition <
tt>FirstOnline <= state <= LastOnline</
tt> must be

Extended error information can be set by VirtualBox components after
unsuccessful or partially successful method invocation. This information
can be retrieved by the calling party as an IVirtualBoxErrorInfo object
and then shown to the client in addition to the plain 32-bit result code.
In MS COM, this interface extends the IErrorInfo interface,
in XPCOM, it extends the nsIException interface. In both cases,
it provides a set of common attributes to retrieve error
Sometimes invocation of some component's method may involve methods of
other components that may also fail (independently of this method's
failure), or a series of non-fatal errors may precede a fatal error that
causes method failure. In cases like that, it may be desirable to preserve
information about all errors happened during method invocation and deliver
it to the caller. The <
link to="#next"/> attribute is intended
specifically for this purpose and allows to represent a chain of errors
through a single IVirtualBoxErrorInfo object set after method invocation.
<
note>errors are stored to a chain in the reverse order,
i.e. the
initial error object you query right after method invocation is the last
error set by the callee, the object it points to in the @a next attribute
is the previous error and so on, up to the first error (which is the last

Usually, it will be the same as the result code returned

likely return E_NOINTERFACE upon unsuccessful component
instantiation attempt, but not the value the component factory
returned. Value is typed 'long', not 'result',

Configure the machine using the appropriate attributes and methods.
Call <

Opens a medium from an existing storage location.
Once a medium has been opened, it can be passed to other VirtualBox
methods, in particular to <
link to="IMachine::attachDevice" />.
Depending on the given device type, the file at the storage location
must be in one of the media formats understood by VirtualBox:
<
li>With a "HardDisk" device type, the file must be a hard disk image
in one of the formats supported by VirtualBox (see
<
link to="ISystemProperties::mediumFormats" />).
After this method succeeds, if the medium is a base medium, it
will be added to the <

<
li>With a "Floppy" device type, the file must be an RAW floppy image.
After this method succeeds, the medium will be added to the

After having been opened, the medium can be found by the <

method and can be attached to virtual machines. See <
link to="IMedium" /> for more details.
The UUID of the newly opened medium will either be retrieved from the
storage location, if the format supports it (
e.g. for hard disk images),
or a new UUID will be randomly generated (
e.g. for ISO and RAW files).
If for some reason you need to change the medium's UUID, use
<

If a differencing hard disk medium is to be opened by this method, the
operation will succeed only if its parent medium and all ancestors,
if any, are already known to this VirtualBox installation (for example,
were opened by this method before).
This method attempts to guess the storage format of the specified medium
by reading medium data at the specified location.
If @a accessMode is ReadWrite (which it should be for hard disks and floppies),
the image is opened for
read/
write access and must have according permissions,
as VirtualBox may actually write status information into the disk's metadata
Note that write access is required for all typical hard disk usage in VirtualBox,
since VirtualBox may need to write metadata such as a UUID into the image.
The only exception is opening a source image temporarily for copying and
cloning (see <

///////////////////////////////////////////////////////////////////////// name="IAppliance" extends="$unknown" uuid="7b148032-4124-4f46-b56a-b48ac1273f5a" Represents a platform-independent appliance in OVF format. An instance of this is returned
by <
link to="IVirtualBox::createAppliance" />, which can then be used to import and export
virtual machines within an appliance with VirtualBox.
The OVF standard suggests two different physical file formats:
<
li>If the appliance is distributed as a set of files, there must be at least one XML descriptor
file that conforms to the OVF standard and carries an <
tt>.ovf</
tt> file extension. If
this descriptor file references other files such as disk images, as OVF appliances typically
do, those additional files must be in the same directory as the descriptor file.</
li>
<
li>If the appliance is distributed as a single file, it must be in TAR format and have the
<
tt>.ova</
tt> file extension. This TAR file must then contain at least the OVF descriptor
files and optionally other files.
At this time, VirtualBox does not not yet support the packed (TAR) variant; support will
be added with a later version.</
li>
<
b>Importing</
b> an OVF appliance into VirtualBox as instances of
<
link to="IMachine" /> involves the following sequence of API calls:
<
li>Call <
link to="IVirtualBox::createAppliance" />. This will create an empty IAppliance object.
<
li>On the new object, call <
link to="#read" /> with the full path of the OVF file you
would like to import. So long as this file is syntactically valid, this will succeed
and fill the appliance object with the parsed data from the OVF file.
<
li>Next, call <
link to="#interpret" />, which analyzes the OVF data and sets up the
contents of the IAppliance attributes accordingly. These can be inspected by a
VirtualBox front-end such as the GUI, and the suggestions can be displayed to the
user. In particular, the <
link to="#virtualSystemDescriptions" /> array contains
instances of <
link to="IVirtualSystemDescription" /> which represent the virtual
systems (machines) in the OVF, which in turn describe the virtual hardware prescribed
by the OVF (network and hardware adapters, virtual disk images, memory size and so on).
The GUI can then give the user the option to confirm
and/
or change these suggestions.
<
li>If desired, call <
link to="IVirtualSystemDescription::setFinalValues" /> for each
virtual system (machine) to override the suggestions made by the <
link to="#interpret" /> routine.
<
li>Finally, call <
link to="#importMachines" /> to create virtual machines in
VirtualBox as instances of <
link to="IMachine" /> that match the information in the
virtual system descriptions. After this call succeeded, the UUIDs of the machines created
can be found in the <
link to="#machines" /> array attribute.
<
b>Exporting</
b> VirtualBox machines into an OVF appliance involves the following steps:
<
li>As with importing, first call <
link to="IVirtualBox::createAppliance" /> to create
an empty IAppliance object.
<
li>For each machine you would like to export, call <
link to="IMachine::export" />
with the IAppliance object you just created. Each such call creates one instance of
<
link to="IVirtualSystemDescription" /> inside the appliance.
<
li>If desired, call <
link to="IVirtualSystemDescription::setFinalValues" /> for each
virtual system (machine) to override the suggestions made by the <
link to="IMachine::export"/> routine.
<
li>Finally, call <
link to="#write" /> with a path specification to have the OVF
<
attribute name="path" type="wstring" readonly="yes">
<
desc>Path to the main file of the OVF appliance, which is either the <
tt>.ovf</
tt> or
the <
tt>.ova</
tt> file passed to <
link to="#read" /> (for import) or
<
link to="#write" /> (for export).
This attribute is empty until one of these methods has been called.
<
attribute name="disks" type="wstring" readonly="yes" safearray="yes">
Array of virtual disk definitions. One such description exists for each
disk definition in the OVF; each string array item represents one such piece of
disk information, with the information fields separated by tab (\\t) characters.
The caller should be prepared for additional fields being appended to
this string in future versions of VirtualBox and therefore check for
the number of tabs in the strings returned.
In the current version, the following eight fields are returned per string
<
li>Disk ID (unique string identifier given to disk)</
li>
<
li>Capacity (unsigned integer indicating the maximum capacity of the disk)</
li>
<
li>Populated size (optional unsigned integer indicating the current size of the

which need not necessarily be the same as the values specified above, since
the image may be compressed or sparse; -1 if not specified)</
li>
<
li>Chunk size (optional unsigned integer if the image is split into chunks;
presently unsupported and always -1)</

Calling this method is the second step of importing an appliance into VirtualBox;

Calling this method is the final step of importing an appliance into VirtualBox;
see <

Since importing the appliance will most probably involve copying and converting
disk images, which can take a long time, this method operates asynchronously and
returns an IProgress object to allow the caller to monitor the progress.

<
method name="getDescription">
<
desc>Returns information about the virtual system as arrays of instruction items. In each array, the
items with the same indices correspond and jointly represent an import instruction for VirtualBox.
The list below identifies the value sets that are possible depending on the
<
link to="VirtualSystemDescriptionType" /> enum value in the array item in @a aTypes[]. In each case,
the array item with the same index in @a aOvfValues[] will contain the original value as contained
in the OVF file (just for informational purposes), and the corresponding item in @a aVBoxValues[]
will contain a suggested value to be used for VirtualBox. Depending on the description type,
the @a aExtraConfigValues[] array item may also be used.
"OS": the guest operating system type. There must be exactly one such array item on import. The
corresponding item in @a aVBoxValues[] contains the suggested guest operating system for VirtualBox.
This will be one of the values listed in <
link to="IVirtualBox::guestOSTypes" />. The corresponding
item in @a aOvfValues[] will contain a numerical value that described the operating system in the OVF.
"Name": the name to give to the new virtual machine. There can be at most one such array item;
if none is present on import, then an automatic name will be created from the operating system
type. The corresponding item im @a aOvfValues[] will contain the suggested virtual machine name
from the OVF file, and @a aVBoxValues[] will contain a suggestion for a unique VirtualBox
<
link to="IMachine" /> name that does not exist yet.
"Description": an arbitrary description.
"License": the EULA section from the OVF, if present. It is the responsibility of the calling
code to display such a license for agreement; the Main API does not enforce any such policy.
Miscellaneous: reserved for future use.
"CPU": the number of CPUs. There can be at most one such item, which will presently be ignored.
"Memory": the amount of guest RAM, in bytes. There can be at most one such array item; if none
is present on import, then VirtualBox will set a meaningful default based on the operating system
"HardDiskControllerIDE": an IDE hard disk controller. There can be at most two such items.
An optional value in @a aOvfValues[] and @a aVBoxValues[] can be "PIIX3" or "PIIX4" to specify
the type of IDE controller; this corresponds to the ResourceSubType element which VirtualBox
The matching item in the @a aRefs[] array will contain an integer that items of the "Harddisk"
type can use to specify which hard disk controller a virtual disk should be connected to.
Note that in OVF, an IDE controller has two channels, corresponding to "master" and "slave"
in traditional terminology, whereas the IDE storage controller that VirtualBox supports in
its virtual machines supports four channels (primary master, primary slave, secondary master,
secondary slave) and thus maps to two IDE controllers in the OVF sense.
"HardDiskControllerSATA": an SATA hard disk controller. There can be at most one such item. This
has no value in @a aOvfValues[] or @a aVBoxValues[].
The matching item in the @a aRefs[] array will be used as with IDE controllers (see above).
"HardDiskControllerSCSI": a SCSI hard disk controller. There can be at most one such item.
The items in @a aOvfValues[] and @a aVBoxValues[] will either be "LsiLogic", "BusLogic" or
"LsiLogicSas". (Note that in OVF, the LsiLogicSas controller is treated as a SCSI controller
whereas VirtualBox considers it a class of storage controllers of its own; see
<
link to="StorageControllerType" />).
The matching item in the @a aRefs[] array will be used as with IDE controllers (see above).
"HardDiskImage": a virtual hard disk, most probably as a reference to an image file. There can be an
arbitrary number of these items, one for each virtual disk image that accompanies the OVF.
The array item in @a aOvfValues[] will contain the file specification from the OVF file (without
a path since the image file should be in the same location as the OVF file itself), whereas the
item in @a aVBoxValues[] will contain a qualified path specification to where VirtualBox uses the
hard disk image. This means that on import the image will be copied and converted from the
"ovf" location to the "vbox" location; on export, this will be handled the other way round.
The matching item in the @a aExtraConfigValues[] array must contain a string of the following
format: "controller=<index>;channel=<c>"
In this string, <index> must be an integer specifying the hard disk controller to connect
the image to. That number must be the index of an array item with one of the hard disk controller
types (HardDiskControllerSCSI, HardDiskControllerSATA, HardDiskControllerIDE).
In addition, <c> must specify the channel to use on that controller. For IDE controllers,
this can be 0 or 1 for master or slave, respectively. For compatibility with VirtualBox versions
before 3.2, the values 2 and 3 (for secondary master and secondary slave) are also supported, but
no longer exported. For SATA and SCSI controllers, the channel can range from 0-29.
"CDROM": a virtual CD-ROM drive. The matching item in @a aExtraConfigValue[] contains the same
attachment information as with "HardDiskImage" items.
"CDROM": a virtual floppy drive. The matching item in @a aExtraConfigValue[] contains the same
attachment information as with "HardDiskImage" items.
"NetworkAdapter": a network adapter. The array item in @a aVBoxValues[] will specify the hardware
for the network adapter, whereas the array item in @a aExtraConfigValues[] will have a string
of the "type=<X>" format, where <X> must be either "NAT" or "Bridged".
"USBController": a USB controller. There can be at most one such item. If and only if such an
item ispresent, USB support will be enabled for the new virtual machine.
"SoundCard": a sound card. There can be at most one such item. If and only if such an item is
present, sound support will be enabled for the new virtual machine. Note that the virtual
machine in VirtualBox will always be presented with the standard VirtualBox soundcard, which
may be different from the virtual soundcard expected by the appliance.

This interface is used in two contexts. First of all, a collection of
objects implementing this interface is stored in the
<
link to="IVirtualBox::machines"/> attribute which lists all the virtual
machines that are currently registered with this VirtualBox
installation. Also, once a session has been opened for the given virtual
machine (
e.g. the virtual machine is running), the machine object
associated with the open session can be queried from the session object;
see <
link to="ISession"/> for details.
The main role of this interface is to expose the settings of the virtual
machine and provide methods to change various aspects of the virtual
machine's configuration. For machine objects stored in the
<
link to="IVirtualBox::machines"/> collection, all attributes are
read-only unless explicitly stated otherwise in individual attribute
In order to change a machine setting, a session for this machine must be
opened using one of the <
link to="IMachine::lockMachine" /> or
<
link to="IMachine::launchVMProcess"/> methods. After the
machine has been successfully locked for a session, a mutable machine object
needs to be queried from the session object and then the desired settings
changes can be applied to the returned object using IMachine attributes and
methods. See the <
link to="ISession"/> interface description for more
information about sessions.
Note that IMachine does not provide methods to control virtual machine
execution (such as start the machine, or power it down) -- these methods
are grouped in a separate interface called <
link to="IConsole" />.

Every time this property is read, the accessibility state of

<
attribute name="name" type="wstring">
Name of the virtual machine.
Besides being used for human-readable identification purposes
everywhere in VirtualBox, the virtual machine name is also used
as a name of the machine's settings file and as a name of the
subdirectory this settings file resides in. Thus, every time you
change the value of this property, the settings file will be
renamed once you call <
link to="#saveSettings"/> to confirm the
change. The containing subdirectory will be also renamed, but
only if it has exactly the same name as the settings file
itself prior to changing this property (for backward compatibility
with previous API releases). The above implies the following
<

If any of the above limitations are hit, <
link to="#saveSettings"/>
will return an appropriate error message explaining the exact
reason and the changes you made to this machine will not be saved.
Starting with VirtualBox 4.0, a “.vbox” extension of the settings
file is recommended, but not enforced. (Previous versions always
used a generic ".xml" extension.)

<
method name="lockMachine">
Locks the machine for the given session to enable the caller
to make changes to the machine or start the VM or control
There are two ways to lock a machine for such uses:
<
li>If you want to make changes to the machine settings,
you must obtain an exclusive write lock on the machine
by setting @a lockType to @c Write.
This will only succeed if no other process has locked
the machine to prevent conflicting changes. Only after
an exclusive write lock has been obtained using this method, one
can change all VM settings or execute the VM in the process
space of the session object. (Note that the latter is only of
interest if you actually want to write a new front-end for
virtual machines; but this API gets called internally by
the existing front-ends such as VBoxHeadless and the VirtualBox
GUI to acquire a write lock on the machine that they are running.)
On success, write-locking the machine for a session creates
a second copy of the IMachine object. It is this second object
upon which changes can be made; in VirtualBox terminology, the
second copy is "mutable". It is only this second, mutable machine
object upon which you can call methods that change the
machine state. After having called this method, you can
obtain this second, mutable machine object using the
<
link to="ISession::machine" /> attribute.
<
li>If you only want to check the machine state or control
machine execution without actually changing machine
settings (
e.g. to get access to VM statistics or take
a snapshot or save the machine state), then set the
@a lockType argument to @c Shared.
If no other session has obtained a lock, you will obtain an
exclusive write lock as described above. However, if another
session has already obtained such a lock, then a link to that
existing session will be established which allows you
to control that existing session.
To find out which type of lock was obtained, you can
inspect <
link to="ISession::type" />, which will have been
set to either @c WriteLock or @c Shared.
In either case, you can get access to the <
link to="IConsole" />
object which controls VM execution.
Also in all of the above cases, one must always call
<
link to="ISession::unlockMachine" /> to release the lock on the machine, or
the machine's state will eventually be set to "Aborted".
To change settings on a machine, the following sequence is typically
<
li>Call this method to obtain an exclusive write lock for the current session.</
li>
<
li>Obtain a mutable IMachine object from <
link to="ISession::machine" />.</
li>

<
method name="launchVMProcess">
Spawns a new process that will execute the virtual machine and obtains a shared
lock on the machine for the calling session.
If launching the VM succeeds, the new VM process will create its own session
and write-lock the machine for it, preventing conflicting changes from other
processes. If the machine is already locked (because it is already running or
because another session has a write lock), launching the VM process will therefore
fail. Reversely, future attempts to obtain a write lock will also fail while the
The caller's session object remains separate from the session opened by the new
VM process. It receives its own <
link to="IConsole" /> object which can be used
to control machine execution, but it cannot be used to change all VM settings
which would be available after a <
link to="#lockMachine" /> call.
The caller must eventually release the session's shared lock by calling
<
link to="ISession::unlockMachine" /> on the local session object once this call
has returned. However, the session's state (see <
link to="ISession::state" />)
will not return to "Unlocked" until the remote session has also unlocked
the machine (
i.e. the machine has stopped running).
Launching a VM process can take some time (a new VM is started in a new process,
for which memory and other resources need to be set up). Because of this,
an <
link to="IProgress" /> object is returned to allow the caller to wait
for this asynchronous operation to be completed. Until then, the caller's
session object remains in the "Unlocked" state, and its <
link to="ISession::machine" />
and <
link to="ISession::console" /> attributes cannot be accessed.
It is recommended to use <
link to="IProgress::waitForCompletion" /> or
similar calls to wait for completion. Completion is signalled when the VM
is powered on. If launching the VM fails, error messages can be queried
via the progress object, if available.
The progress object will have at least 2 sub-operations. The first
operation covers the period up to the new VM process calls powerUp.
The subsequent operations mirror the <
link to="IConsole::powerUp"/>
progress object. Because <
link to="IConsole::powerUp"/> may require
some extra sub-operations, the <
link to="IProgress::operationCount"/>
may change at the completion of operation.
For details on the teleportation progress operation, see
<
link to="IConsole::powerUp"/>.
The @a environment argument is a string containing definitions of
environment variables in the following format:
where <
tt>\\n</
tt> is the new line character. These environment
variables will be appended to the environment of the VirtualBox server
process. If an environment variable exists both in the server process
and in this list, the value from this list takes precedence over the
server's variable. If the value of the environment variable is
omitted, this variable will be removed from the resulting environment.
If the environment string is @c null or empty, the server environment
is inherited by the started process as is.

<
method name="unregister">
Unregisters a machine previously registered with
<
link to="IVirtualBox::registerMachine"/> and optionally do additional
cleanup before the machine is unregistered.
This method does not delete any files. It only changes the machine configuration and
the list of registered machines in the VirtualBox object. To delete the files which
belonged to the machine, including the XML file of the machine itself, call
<
link to="#delete"/>, optionally with the array of IMedium objects which was returned
How thoroughly this method cleans up the machine configuration before unregistering
the machine depends on the @a cleanupMode argument.
<
li>With "UnregisterOnly", the machine will only be unregistered, but no additional
cleanup will be performed. The call will fail if the machine is in "Saved" state
or has any snapshots or any media attached (see <
link to="IMediumAttachment" />).
It is the responsibility of the caller to delete all such configuration in this mode.
In this mode, the API behaves like the former @c IVirtualBox::unregisterMachine() API
<
li>With "DetachAllReturnNone", the call will succeed even if the machine is in "Saved"
state or if it has snapshots or media attached. All media attached to the current machine
state or in snapshots will be detached. No medium objects will be returned;
all of the machine's media will remain open.</
li>
<
li>With "DetachAllReturnHardDisksOnly", the call will behave like with "DetachAllReturnNone",
except that all the hard disk medium objects which were detached from the machine will
be returned as an array. This allows for quickly passing them to the <
link to="#delete" />
API for closing and deletion.</
li>
<
li>With "Full", the call will behave like with "DetachAllReturnHardDisksOnly", except
that all media will be returned in the array, including removable media like DVDs and
floppies. This might be useful if the user wants to inspect in detail which media were
attached to the machine. Be careful when passing the media array to <
link to="#delete" />
in that case because users will typically want to preserve ISO and RAW image files.</
li>
A typical implementation will use "DetachAllReturnHardDisksOnly" and then pass the
resulting IMedium array to <
link to="#delete"/>. This way, the machine is completely
deleted with all its saved states and hard disk images, but images for removable
drives (such as ISO and RAW files) will remain on disk.
This API does not verify whether the media files returned in the array are still
attached to other machines (
i.e. shared between several machines). If such a shared
image is passed to <
link to="#delete" /> however, closing the image will fail there
and the image will be silently skipped.
This API may, however, move media from this machine's media registry to other media
registries (see <
link to="IMedium" /> for details on media registries). For machines
created with VirtualBox 4.0 or later, if media from this machine's media registry
are also attached to another machine (shared attachments), each such medium will be
moved to another machine's registry. This is because without this machine's media
registry, the other machine cannot find its media any more and would become inaccessible.
This API implicitly calls <
link to="#saveSettings"/> to save all current machine settings
before unregistering it. It may also silently call <
link to="#saveSettings"/> on other machines
if media are moved to other machines' media registries.
After successful method invocation, the <
link to="IMachineRegisteredEvent"/> event
The call will fail if the machine is currently locked (see <
link to="ISession" />).
If the given machine is inaccessible (see <
link to="#accessible"/>), it
will be unregistered and fully uninitialized right afterwards. As a result,
the returned machine object will be unusable and an attempt to call
<
b>any</
b> method will return the "Object not ready" error.

Deletes the files associated with this machine from disk. If medium objects are passed
in with the @a aMedia argument, they are closed and, if closing was successful, their
storage files are deleted as well. For convenience, this array of media files can be
the same as the one returned from a previous <
link to="#unregister" /> call.
This method must only be called on machines which are either write-locked (
i.e. on instances
returned by <
link to="ISession::machine"/>) or on unregistered machines (
i.e. not yet
registered machines created by <
link to="IVirtualBox::createMachine"/> or opened by
<
link to="IVirtualBox::openMachine"/>, or after having called <
link to="#unregister"/>).
The following files will be deleted by this method:
<
li>If <
link to="#unregister" /> had been previously called with a @a cleanupMode
argument other than "UnregisterOnly", this will delete all saved state files that
the machine had in use; possibly one if the machine was in "Saved" state and one
for each online snapshot that the machine had.</
li>
<
li>On each medium object passed in the @a aMedia array, this will call
<
link to="IMedium::close" />. If that succeeds, this will attempt to delete the
medium's storage on disk. Since the <
link to="IMedium::close"/> call will fail if the medium is still
in use,
e.g. because it is still attached to a second machine; in that case the
storage will not be deleted.</
li>
<
li>Finally, the machine's own XML file will be deleted.</
li>
Since deleting large disk image files can be a time-consuming I/O operation, this
method operates asynchronously and returns an IProgress object to allow the caller
to monitor the progress. There will be one sub-operation for each file that is
being deleted (saved state or medium storage file).
<

method successfully returns.

This operation is very fast if the snapshot subtree does not include
the current state. It is still significantly faster than deleting the
snapshots one by one if the current state is in the subtree and there
are more than one snapshots from current state to the snapshot which
marks the subtree, since it eliminates the incremental image merging.

///////////////////////////////////////////////////////////////////////// name="IProgress" extends="$unknown" uuid="c20238e4-3221-4d3f-8891-81ce92d9f913" The IProgress interface is used to track and control
asynchronous tasks within VirtualBox.
An instance of this is returned every time VirtualBox starts
an asynchronous task (in other words, a separate thread) which
continues to run after a method call returns. For example,
<
link to="IConsole::saveState" />, which saves the state of
a running virtual machine, can take a long time to complete.
To be able to display a progress bar, a user interface such as
the VirtualBox graphical user interface can use the IProgress
object returned by that method.
Note that IProgress is a "read-only" interface in the sense
that only the VirtualBox internals behind the Main API can
create and manipulate progress objects, whereas client code
can only use the IProgress object to monitor a task's
progress and, if <
link to="#cancelable" /> is @c true,
cancel the task by calling <
link to="#cancel" />.
A task represented by IProgress consists of either one or
several sub-operations that run sequentially, one by one (see
<
link to="#operation" /> and <
link to="#operationCount" />).
Every operation is identified by a number (starting from 0)
and has a separate description.
You can find the individual percentage of completion of the current
operation in <
link to="#operationPercent" /> and the
percentage of completion of the task as a whole
in <
link to="#percent" />.
Similarly, you can wait for the completion of a particular
operation via <
link to="#waitForOperationCompletion" /> or
for the completion of the whole task via

Together with the differencing media that are created
when a snapshot is taken, a machine can be brought back to
the exact state it was in when the snapshot was taken.
The ISnapshot interface has no methods, only attributes; snapshots
are controlled through methods of the <
link to="IConsole" /> interface
which also manage the media associated with the snapshot.
The following operations exist:
<
li><
link to="IConsole::takeSnapshot"/> creates a new snapshot
by creating new, empty differencing images for the machine's
media and saving the VM settings and (if the VM is running)
the current VM state in the snapshot.
The differencing images will then receive all data written to
the machine's media, while their parent (base) images
remain unmodified after the snapshot has been taken (see
<
link to="IMedium" /> for details about differencing images).
This simplifies restoring a machine to the state of a snapshot:
only the differencing images need to be deleted.
The current machine state is not changed by taking a snapshot
except that <
link to="IMachine::currentSnapshot" /> is set to
the newly created snapshot, which is also added to the machine's
<
li><
link to="IConsole::restoreSnapshot"/> resets a machine to
the state of a previous snapshot by deleting the differencing
image of each of the machine's media and setting the machine's
settings and state to the state that was saved in the snapshot (if any).
This destroys the machine's current state. After calling this,
<
link to="IMachine::currentSnapshot" /> points to the snapshot
<
li><
link to="IConsole::deleteSnapshot"/> deletes a snapshot
without affecting the current machine state.
This does not change the current machine state, but instead frees the
resources allocated when the snapshot was taken: the settings and machine
state file are deleted (if any), and the snapshot's differencing image for
each of the machine's media gets merged with its parent image.
Neither the current machine state nor other snapshots are affected
by this operation, except that parent media will be modified
to contain the disk data associated with the snapshot being deleted.
When deleting the current snapshot, the <
link to="IMachine::currentSnapshot" />
attribute is set to the current snapshot's parent or NULL if it
has no parent. Otherwise the attribute is unchanged.
Each snapshot contains a copy of virtual machine's settings (hardware
configuration etc.). This copy is contained in an immutable (read-only)
instance of <
link to="IMachine" /> which is available from the snapshot's
<
link to="#machine" /> attribute. When restoring the snapshot, these
settings are copied back to the original machine.
In addition, if the machine was running when the
snapshot was taken (<
link to="IMachine::state"/> is <
link to="MachineState_Running"/>),
the current VM state is saved in the snapshot (similarly to what happens
when a VM's state is saved). The snapshot is then said to be <
i>online</
i>
because when restoring it, the VM will be running.
If the machine was in <
link to="MachineState_Saved">saved</
link> saved,
the snapshot receives a copy of the execution state file
(<
link to="IMachine::stateFilePath"/>).
Otherwise, if the machine was not running (<
link to="MachineState_PoweredOff"/>
or <
link to="MachineState_Aborted"/>), the snapshot is <
i>offline</
i>;
it then contains a so-called "zero execution state", representing a
machine that is powered off.

name="IMediumAttachment" extends="$unknown" uuid="aa4b4840-934f-454d-9a28-23e8f4235edf" The IMediumAttachment interface links storage media to virtual machines.
For each medium (<
link to="IMedium"/>) which has been attached to a
storage controller (<
link to="IStorageController"/>) of a machine
(<
link to="IMachine"/>) via the <
link to="IMachine::attachDevice" />
method, one instance of IMediumAttachment is added to the machine's
<
link to="IMachine::mediumAttachments"/> array attribute.
Each medium attachment specifies the storage controller as well as a
port and device number and the IMedium instance representing a virtual
hard disk or floppy or DVD image.
For removable media (DVDs or floppies), there are two additional
options. For one, the IMedium instance can be @c null to represent
an empty drive with no media inserted (see <
link to="IMachine::mountMedium" />);
secondly, the medium can be one of the pseudo-media for host drives
listed in <
link to="IHost::DVDDrives"/> or <
link to="IHost::floppyDrives"/>.
<
h3>Attaching Hard Disks</
h3>
Hard disks are attached to virtual machines using the
<
link to="IMachine::attachDevice"/> method and detached using the
<
link to="IMachine::detachDevice"/> method. Depending on a medium's
type (see <
link to="IMedium::type" />), hard disks are attached either
<
i>directly</
i> or <
i>indirectly</
i>.
When a hard disk is being attached directly, it is associated with the
virtual machine and used for hard disk operations when the machine is
running. When a hard disk is being attached indirectly, a new differencing
hard disk linked to it is implicitly created and this differencing hard
disk is associated with the machine and used for hard disk operations.
This also means that if <
link to="IMachine::attachDevice"/> performs
a direct attachment then the same hard disk will be returned in response
to the subsequent <
link to="IMachine::getMedium"/> call; however if
an indirect attachment is performed then
<
link to="IMachine::getMedium"/> will return the implicitly created
differencing hard disk, not the original one passed to <
link to="IMachine::attachDevice"/>. In detail:
<
li><
b>Normal base</
b> hard disks that do not have children (
i.e. differencing hard disks linked to them) and that are not already
attached to virtual machines in snapshots are attached <
b>directly</
b>.
Otherwise, they are attached <
b>indirectly</
b> because having
dependent children or being part of the snapshot makes it impossible
to modify hard disk contents without breaking the integrity of the
dependent party. The <
link to="IMedium::readOnly"/> attribute allows to
quickly determine the kind of the attachment for the given hard
disk. Note that if a normal base hard disk is to be indirectly
attached to a virtual machine with snapshots then a special
procedure called <
i>smart attachment</
i> is performed (see below).</
li>
<
li><
b>Normal differencing</
b> hard disks are like normal base hard disks:
they are attached <
b>directly</
b> if they do not have children and are
not attached to virtual machines in snapshots, and <
b>indirectly</
b>
otherwise. Note that the smart attachment procedure is never performed
for differencing hard disks.</
li>
<
li><
b>Immutable</
b> hard disks are always attached <
b>indirectly</
b> because
they are designed to be non-writable. If an immutable hard disk is
attached to a virtual machine with snapshots then a special
procedure called smart attachment is performed (see below).</
li>
<
li><
b>Writethrough</
b> hard disks are always attached <
b>directly</
b>,
also as designed. This also means that writethrough hard disks cannot
have other hard disks linked to them at all.</
li>
<
li><
b>Shareable</
b> hard disks are always attached <
b>directly</
b>,
also as designed. This also means that shareable hard disks cannot
have other hard disks linked to them at all. They behave almost
like writethrough hard disks, except that shareable hard disks can
be attached to several virtual machines which are running, allowing
concurrent accesses. You need special cluster software running in
the virtual machines to make use of such disks.</
li>
Note that the same hard disk, regardless of its type, may be attached to
more than one virtual machine at a time. In this case, the machine that is
started first gains exclusive access to the hard disk and attempts to
start other machines having this hard disk attached will fail until the
first machine is powered down.
Detaching hard disks is performed in a <
i>deferred</
i> fashion. This means
that the given hard disk remains associated with the given machine after a
successful <
link to="IMachine::detachDevice"/> call until
<
link to="IMachine::saveSettings"/> is called to save all changes to
machine settings to disk. This deferring is necessary to guarantee that
the hard disk configuration may be restored at any time by a call to
<
link to="IMachine::discardSettings"/> before the settings
Note that if <
link to="IMachine::discardSettings"/> is called after
indirectly attaching some hard disks to the machine but before a call to
<
link to="IMachine::saveSettings"/> is made, it will implicitly delete
all differencing hard disks implicitly created by
<
link to="IMachine::attachDevice"/> for these indirect attachments.
Such implicitly created hard disks will also be immediately deleted when
detached explicitly using the <
link to="IMachine::detachDevice"/>
call if it is made before <
link to="IMachine::saveSettings"/>. This
implicit deletion is safe because newly created differencing hard
disks do not contain any user data.
However, keep in mind that detaching differencing hard disks that were
implicitly created by <
link to="IMachine::attachDevice"/>
before the last <
link to="IMachine::saveSettings"/> call will
<
b>not</
b> implicitly delete them as they may already contain some data
(for example, as a result of virtual machine execution). If these hard
disks are no more necessary, the caller can always delete them explicitly
using <
link to="IMedium::deleteStorage"/> after they are actually de-associated
from this machine by the <
link to="IMachine::saveSettings"/> call.
<
h3>Smart Attachment</
h3>
When normal base or immutable hard disks are indirectly attached to a
virtual machine then some additional steps are performed to make sure the
virtual machine will have the most recent "view" of the hard disk being
attached. These steps include walking through the machine's snapshots
starting from the current one and going through ancestors up to the first
snapshot. Hard disks attached to the virtual machine in all
of the encountered snapshots are checked whether they are descendants of
the given normal base or immutable hard disk. The first found child (which
is the differencing hard disk) will be used instead of the normal base or
immutable hard disk as a parent for creating a new differencing hard disk
that will be actually attached to the machine. And only if no descendants
are found or if the virtual machine does not have any snapshots then the
normal base or immutable hard disk will be used itself as a parent for
this differencing hard disk.
It is easier to explain what smart attachment does using the
Snapshot 4 (none) Snapshot 4 (none)
CurState (none) CurState (D3->
D2.vdi)
The first column is the virtual machine configuration before the base hard
disk <
tt>
B.vdi</
tt> is attached, the second column shows the machine after
this hard disk is attached. Constructs like <
tt>D1->
B.vdi</
tt> and similar
mean that the hard disk that is actually attached to the machine is a
differencing hard disk, <
tt>
D1.vdi</
tt>, which is linked to (based on)
another hard disk, <
tt>
B.vdi</
tt>.
As we can see from the example, the hard disk <
tt>
B.vdi</
tt> was detached
from the machine before taking Snapshot 4. Later, after Snapshot 4 was
taken, the user decides to attach <
tt>
B.vdi</
tt> again. <
tt>
B.vdi</
tt> has
dependent child hard disks (<
tt>
D1.vdi</
tt>, <
tt>
D2.vdi</
tt>), therefore
it cannot be attached directly and needs an indirect attachment (
i.e. implicit creation of a new differencing hard disk). Due to the smart
attachment procedure, the new differencing hard disk
<
tt>
B.vdi</
tt> itself, since <
tt>
D2.vdi</
tt> is the most recent view of
<
tt>
B.vdi</
tt> existing for this snapshot branch of the given virtual
Note that if there is more than one descendant hard disk of the given base
hard disk found in a snapshot, and there is an exact device, channel and
bus match, then this exact match will be used. Otherwise, the youngest
descendant will be picked up.
There is one more important aspect of the smart attachment procedure which
is not related to snapshots at all. Before walking through the snapshots
as described above, the backup copy of the current list of hard disk
attachment is searched for descendants. This backup copy is created when
the hard disk configuration is changed for the first time after the last
<
link to="IMachine::saveSettings"/> call and used by
<
link to="IMachine::discardSettings"/> to undo the recent hard disk
changes. When such a descendant is found in this backup copy, it will be
simply re-attached back, without creating a new differencing hard disk for
it. This optimization is necessary to make it possible to re-attach the
base or immutable hard disk to a different bus, channel or device slot
without losing the contents of the differencing hard disk actually
attached to the machine in place of it.

name="IMedium" extends="$unknown" uuid="f55ce3ec-b856-4d07-ae33-826072b332c3" The IMedium interface represents virtual storage for a machine's
hard disks,
CD/
DVD or floppy drives. It will typically represent
a disk image on the host, for example a VDI or VMDK file representing
a virtual hard disk, or an ISO or RAW file representing virtual
removable media, but can also point to a network location (
e.g. Instances of IMedium are connected to virtual machines by way of medium
attachments, which link the storage medium to a particular device slot
of a storage controller of the virtual machine.
In the VirtualBox API, virtual storage is therefore always represented
by the following chain of object links:
<
li><
link to="IMachine::storageControllers"/> contains an array of
storage controllers (IDE, SATA, SCSI, SAS or a floppy controller;
these are instances of <
link to="IStorageController"/>).</
li>
<
li><
link to="IMachine::mediumAttachments"/> contains an array of
medium attachments (instances of <
link to="IMediumAttachment"/>
created by <
link to="IMachine::attachDevice" />),
each containing a storage controller from the above array, a
port/
device specification, and an instance of IMedium representing
the medium storage (image file).
For removable media, the storage medium is optional; a medium
attachment with no medium represents a
CD/
DVD or floppy drive
with no medium inserted. By contrast, hard disk attachments
will always have an IMedium object attached.</
li>
<
li>Each IMedium in turn points to a storage unit (such as a file
on the host computer or a network resource) that holds actual
data. This location is represented by the <
link to="#location"/>
Existing media are opened using <
link to="IVirtualBox::openMedium"/>;
new hard disk media can be created with the VirtualBox API using the
<
link to="IVirtualBox::createHardDisk"/> method. Differencing hard
disks (see below) are usually implicitly created by VirtualBox as
needed, but may also be created explicitly using <
link to="#createDiffStorage"/>.
VirtualBox cannot create
CD/
DVD or floppy images (ISO and RAW files); these
should be created with external tools and then opened from within VirtualBox.
Only for
CD/
DVDs and floppies, an IMedium instance can also represent a host
drive. In that case the <
link to="#id" /> attribute contains the UUID of
one of the drives in <
link to="IHost::DVDDrives" /> or <
link to="IHost::floppyDrives" />.
<
h3>Media registries</
h3>
When a medium has been opened or created using one of the aforementioned
APIs, it becomes "known" to VirtualBox. Known media can be attached
to virtual machines and accessed through <
link to="IVirtualBox::findMedium"/>.
They also appear in the global
<
link to="IVirtualBox::hardDisks" />,
<
link to="IVirtualBox::DVDImages" /> and
<
link to="IVirtualBox::floppyImages" /> arrays.
Prior to VirtualBox 4.0, opening a medium added it to a global media registry
in the
VirtualBox.xml file, which was shared between all machines and made
transporting machines and their media from one host to another difficult.
Starting with VirtualBox 4.0, media are only added to a registry when they are
<
i>attached</
i> to a machine using <
link to="IMachine::attachDevice" />. For
backwards compatibility, which registry a medium is added to depends on which
VirtualBox version created a machine:
<
li>If the medium has first been attached to a machine which was created by
VirtualBox 4.0 or later, it is added to that machine's media registry in
the machine XML settings file. This way all information about a machine's
media attachments is contained in a single file and can be transported
<
li>For older media attachments (
i.e. if the medium was first attached to a
machine which was created with a VirtualBox version before 4.0), media
continue to be registered in the global VirtualBox settings file, for
backwards compatibility.</
li>
See <
link to="IVirtualBox::openMedium" /> for more information.
Media are removed from media registries by the <
link to="IMedium::close"/>,
<
link to="#deleteStorage"/> and <
link to="#mergeTo"/> methods.
<
h3>Accessibility checks</
h3>
VirtualBox defers media accessibility checks until the <
link to="#refreshState" />
method is called explicitly on a medium. This is done to make the VirtualBox object
ready for serving requests as fast as possible and let the end-user
application decide if it needs to check media accessibility right away or not.
As a result, when VirtualBox starts up (
e.g. the VirtualBox
object gets created for the first time), all known media are in the
"Inaccessible" state, but the value of the <
link to="#lastAccessError"/>
attribute is an empty string because no actual accessibility check has
After calling <
link to="#refreshState" />, a medium is considered
<
i>accessible</
i> if its storage unit can be read. In that case, the
<
link to="#state"/> attribute has a value of "Created". If the storage
unit cannot be read (for example, because it is located on a disconnected
network resource, or was accidentally deleted outside VirtualBox),
the medium is considered <
i>inaccessible</
i>, which is indicated by the
"Inaccessible" state. The exact reason why the medium is inaccessible can be
obtained by reading the <
link to="#lastAccessError"/> attribute.
There are five types of medium behavior which are stored in the
<
link to="#type"/> attribute (see <
link to="MediumType" />) and
which define the medium's behavior with attachments and snapshots.
All media can be also divided in two groups: <
i>base</
i> media and
<
i>differencing</
i> media. A base medium contains all sectors of the
medium data in its own storage and therefore can be used independently.
In contrast, a differencing medium is a "delta" to some other medium and
contains only those sectors which differ from that other medium, which is
then called a <
i>parent</
i>. The differencing medium is said to be
<
i>linked to</
i> that parent. The parent may be itself a differencing
medium, thus forming a chain of linked media. The last element in that
chain must always be a base medium. Note that several differencing
media may be linked to the same parent medium.
Differencing media can be distinguished from base media by querying the
<
link to="#parent"/> attribute: base media do not have parents they would
depend on, so the value of this attribute is always @c null for them.
Using this attribute, it is possible to walk up the medium tree (from the
child medium to its parent). It is also possible to walk down the tree
using the <
link to="#children"/> attribute.
Note that the type of all differencing media is "normal"; all other
values are meaningless for them. Base media may be of any type.
<
h3>Automatic composition of the file name part</
h3>
Another extension to the <
link to="IMedium::location"/> attribute is that
there is a possibility to cause VirtualBox to compose a unique value for
the file name part of the location using the UUID of the hard disk. This
applies only to hard disks in <
link to="MediumState_NotCreated"/> state,
e.g. before the storage unit is created, and works as follows. You set the
value of the <
link to="IMedium::location"/> attribute to a location
specification which only contains the path specification but not the file
name part and ends with either a forward slash or a backslash character.
In response, VirtualBox will generate a new UUID for the hard disk and
compose the file name using the following pattern:
<path>/{<uuid>}.<ext>
where <
tt><path></
tt> is the supplied path specification,
<
tt><uuid></
tt> is the newly generated UUID and <
tt><ext></
tt>
is the default extension for the storage format of this hard disk. After
that, you may call any of the methods that create a new hard disk storage
unit and they will use the generated UUID and file name.
<
attribute name="id" type="uuid" mod="string" readonly="yes">
UUID of the medium. For a newly created medium, this value is a randomly
For media in one of MediumState_NotCreated, MediumState_Creating or
MediumState_Deleting states, the value of this property is undefined
and will most likely be an empty UUID.
<
attribute name="description" type="wstring">
Optional description of the medium. For a newly created medium the value
of this attribute is an empty string.
Medium types that don't support this attribute will return E_NOTIMPL in
attempt to get or set this attribute's value.
For some storage types, reading this attribute may return an outdated
(last known) value when <
link to="#state"/> is <
link to="MediumState_Inaccessible"/> or <
link to="MediumState_LockedWrite"/> because the value of this attribute is
stored within the storage unit itself. Also note that changing the
attribute value is not possible in such case, as well as when the
medium is the <
link to="MediumState_LockedRead"/> state.
<
attribute name="state" type="MediumState" readonly="yes">
Returns the current medium state, which is the last state set by
the accessibility check performed by <

Location of the storage unit holding medium data.
The format of the location string is medium type specific. For medium
types using regular files in a host's file system, the location
string is the full file name.
Some medium types may support changing the storage unit location by
simply changing the value of this property. If this operation is not
supported, the implementation will return E_NOTIMPL in attempt to set

in the host's file system, the given file name may be either relative to
the <

absolute. Note that if the given location specification does not contain
the file extension part then a proper default extension will be
automatically appended by the implementation depending on the medium type.
<
attribute name="name" type="wstring" readonly="yes">
Name of the storage unit holding medium data.
The returned string is a short version of the <
link to="#location"/>
attribute that is suitable for representing the medium in situations
where the full location specification is too long (such as lists
and comboboxes in GUI frontends). This string is also used by frontends
to sort the media list alphabetically when needed.

system, the value of this attribute is just the file name (+ extension),
without the path specification.

The refresh, if performed, may take a long time (several seconds or even

Locks this medium for reading.
A read lock is shared: many clients can simultaneously lock the
same medium for reading unless it is already locked for writing (see
<
link to="#lockWrite"/>) in which case an error is returned.
When the medium is locked for reading, it cannot be modified
from within VirtualBox. This means that any method that changes
the properties of this medium or contents of the storage unit
will return an error (unless explicitly stated otherwise). That
includes an attempt to start a virtual machine that wants to
When the virtual machine is started up, it locks for reading all
media it uses in read-only mode. If some medium cannot be locked
for reading, the startup procedure will fail.
A medium is typically locked for reading while it is used by a running
virtual machine but has a depending differencing image that receives
the actual write operations. This way one base medium can have
multiple child differencing images which can be written to
simultaneously. Read-only media such as DVD and floppy images are
also locked for reading only (so they can be in use by multiple
machines simultaneously).
A medium is also locked for reading when it is the source of a
write operation such as <
link to="#cloneTo"/> or <
link to="#mergeTo"/>.
The medium locked for reading must be unlocked using the <
link to="#unlockRead"/> method. Calls to <
link to="#lockRead"/>
can be nested and must be followed by the same number of paired
<
link to="#unlockRead"/> calls.
This method sets the medium state (see <
link to="#state"/>) to
"LockedRead" on success. The medium's previous state must be
one of "Created", "Inaccessible" or "LockedRead".

Locks this medium for writing.
A write lock, as opposed to <

exclusive: there may be only one client holding a write lock,
and there may be no read locks while the write lock is held.
As a result, read-locking fails if a write lock is held, and
write-locking fails if either a read or another write lock is held.
When a medium is locked for writing, it cannot be modified
from within VirtualBox, and it is not guaranteed that the values
of its properties are up-to-date. Any method that changes the
properties of this medium or contents of the storage unit will
return an error (unless explicitly stated otherwise).
When a virtual machine is started up, it locks for writing all
media it uses to write data to. If any medium could not be locked
for writing, the startup procedure will fail. If a medium has
differencing images, then while the machine is running, only
the last ("leaf") differencing image is locked for writing,
whereas its parents are locked for reading only.

Starts merging the contents of this medium and all intermediate
differencing media in the chain to the given target medium.
The target medium must be either a descendant of this medium or
its ancestor (otherwise this method will immediately return a failure).
It follows that there are two logical directions of the merge operation:
from ancestor to descendant (<
i>forward merge</
i>) and from descendant to
ancestor (<
i>backward merge</
i>). Let us consider the following medium
<
pre>Base <- Diff_1 <- Diff_2</
pre>
Here, calling this method on the <
tt>Base</
tt> medium object with
<
tt>Diff_2</
tt> as an argument will be a forward merge; calling it on
<
tt>Diff_2</
tt> with <
tt>Base</
tt> as an argument will be a backward
merge. Note that in both cases the contents of the resulting medium
will be the same, the only difference is the medium object that takes
the result of the merge operation. In case of the forward merge in the
above example, the result will be written to <
tt>Diff_2</
tt>; in case of
the backward merge, the result will be written to <
tt>Base</
tt>. In
other words, the result of the operation is always stored in the target
Upon successful operation completion, the storage units of all media in
the chain between this (source) medium and the target medium, including
the source medium itself, will be automatically deleted and the
relevant medium objects (including this medium) will become
uninitialized. This means that any attempt to call any of
their methods or attributes will fail with the
<
tt>"Object not ready" (E_ACCESSDENIED)</
tt> error. Applied to the above
example, the forward merge of <
tt>Base</
tt> to <
tt>Diff_2</
tt> will
delete and uninitialize both <
tt>Base</
tt> and <
tt>Diff_1</
tt> media.
Note that <
tt>Diff_2</
tt> in this case will become a base medium
itself since it will no longer be based on any other medium.
Considering the above, all of the following conditions must be met in
order for the merge operation to succeed:
Neither this (source) medium nor any intermediate
differencing medium in the chain between it and the target
medium is attached to any virtual machine.
Neither the source medium nor the target medium is an
<
link to="MediumType_Immutable"/> medium.
The part of the medium tree from the source medium to the
target medium is a linear chain,
i.e. all medium in this
chain have exactly one child which is the next medium in this
chain. The only exception from this rule is the target medium in
the forward merge operation; it is allowed to have any number of
child media because the merge operation will not change its
logical contents (as it is seen by the guest OS or by children).
None of the involved media are in
<
link to="MediumState_LockedRead"/> or
<
link to="MediumState_LockedWrite"/> state.
This (source) medium and all intermediates will be placed to <
link to="MediumState_Deleting"/> state and the target medium will be

duration of this operation.

Starts creating a clone of this medium in the format and at the
location defined by the @a target argument.
The target medium must be either in <
link to="MediumState_NotCreated"/>
state (
i.e. must not have an existing storage unit) or in
<
link to="MediumState_Created"/> state (
i.e. created and not locked, and
big enough to hold the data or else the copy will be partial). Upon
successful completion, the cloned medium will contain exactly the
same sector data as the medium being cloned, except that in the
first case a new UUID for the clone will be randomly generated, and in
the second case the UUID will remain unchanged.
The @a parent argument defines which medium will be the parent
of the clone. Passing a @c null reference indicates that the clone will
be a base image,
i.e. completely independent. It is possible to specify
an arbitrary medium for this parameter, including the parent of the
medium which is being cloned. Even cloning to a child of the source
medium is possible. Note that when cloning to an existing image, the
@a parent argument is ignored.
After the returned progress object reports that the operation is

is usually much lower than using the clone operation.

There are two modes of working with the video buffer of the virtual
machine. The <
i>indirect</
i> mode implies that the IFramebuffer
implementation allocates a memory buffer for the requested display mode
and provides it to the virtual machine. In <
i>direct</
i> mode, the
IFramebuffer implementation uses the memory buffer allocated and owned
by the virtual machine. This buffer represents the video memory of the
emulated video adapter (so called <
i>guest VRAM</
i>). The direct mode is
usually faster because the implementation gets a raw pointer to the
guest VRAM buffer which it can directly use for visualizing the contents
of the virtual display, as opposed to the indirect mode where the
contents of guest VRAM are copied to the memory buffer provided by
the implementation every time a display update occurs.
It is important to note that the direct mode is really fast only when
the implementation uses the given guest VRAM buffer directly, for
example, by blitting it to the window representing the virtual machine's
display, which saves at least one copy operation comparing to the
indirect mode. However, using the guest VRAM buffer directly is not
always possible: the format and the color depth of this buffer may be
not supported by the target window, or it may be unknown (opaque) as in
case of text or non-linear multi-plane VGA video modes. In this case,
the indirect mode (that is always available) should be used as a
fallback: when the guest VRAM contents are copied to the
implementation-provided memory buffer, color and format conversion is
done automatically by the underlying code.
The @a pixelFormat parameter defines whether the direct mode is
available or not. If @a pixelFormat is <
link to="FramebufferPixelFormat_Opaque"/> then direct access to the guest
VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
@a bytesPerLine parameters must be ignored and the implementation must use
the indirect mode (where it provides its own buffer in one of the
supported formats). In all other cases, @a pixelFormat together with
@a bitsPerPixel and @a bytesPerLine define the format of the video memory
buffer pointed to by the @a VRAM parameter and the implementation is
free to choose which mode to use. To indicate that this frame buffer uses
the direct mode, the implementation of the <
link to="#usesGuestVRAM"/>
attribute must return @c true and <
link to="#address"/> must
return exactly the same address that is passed in the @a VRAM parameter
of this method; otherwise it is assumed that the indirect strategy is
The @a width and @a height parameters represent the size of the
requested display mode in both modes. In case of indirect mode, the
provided memory buffer should be big enough to store data of the given
display mode. In case of direct mode, it is guaranteed that the given
@a VRAM buffer contains enough space to represent the display mode of the
given size. Note that this frame buffer's <
link to="#width"/> and <
link to="#height"/> attributes must return exactly the same values as
passed to this method after the resize is completed (see below).
The @a finished output parameter determines if the implementation has
finished resizing the frame buffer or not. If, for some reason, the
resize cannot be finished immediately during this call, @a finished
must be set to @c false, and the implementation must call
<
link to="IDisplay::resizeCompleted"/> after it has returned from
this method as soon as possible. If @a finished is @c false, the
machine will not call any frame buffer methods until
<
link to="IDisplay::resizeCompleted"/> is called.
Note that if the direct mode is chosen, the <
link to="#bitsPerPixel"/>,
<
link to="#bytesPerLine"/> and <
link to="#pixelFormat"/> attributes of
this frame buffer must return exactly the same values as specified in the
parameters of this method, after the resize is completed. If the
indirect mode is chosen, these attributes must return values describing
the format of the implementation's own memory buffer <
link to="#address"/> points to. Note also that the <
link to="#bitsPerPixel"/>
value must always correlate with <
link to="#pixelFormat"/>. Note that
the <
link to="#pixelFormat"/> attribute must never return <
link to="FramebufferPixelFormat_Opaque"/> regardless of the selected mode.
This method is called by the IDisplay object under the
<

implementation. If this method returns @c false in @a finished, then
this lock is not released until

///////////////////////////////////////////////////////////////////////// name="IUSBDeviceFilter" extends="$unknown" uuid="d6831fb4-1a94-4c2c-96ef-8d0d6192066d" The IUSBDeviceFilter interface represents an USB device filter used
to perform actions on a group of USB devices.
This type of filters is used by running virtual machines to
automatically capture selected USB devices once they are physically
attached to the host computer.
A USB device is matched to the given device filter if and only if all
attributes of the device match the corresponding attributes of the
filter (that is, attributes are joined together using the logical AND
operation). On the other hand, all together, filters in the list of
filters carry the semantics of the logical OR operation. So if it is
desirable to create a match like "this vendor id OR this product id",
one needs to create two filters and specify "any match" (see below)
All filter attributes used for matching are strings. Each string
is an expression representing a set of values of the corresponding
device attribute, that will match the given filter. Currently, the
following filtering expressions are supported:
<
li><
i>Interval filters</
i>. Used to specify valid intervals for
integer device attributes (Vendor ID, Product ID and Revision).
The format of the string is:
<
tt>int:((m)|([m]-[n]))(,(m)|([m]-[n]))*</
tt>
where <
tt>m</
tt> and <
tt>n</
tt> are integer numbers, either in octal
(starting from <
tt>0</
tt>), hexadecimal (starting from <
tt>0x</
tt>)
or decimal (otherwise) form, so that <
tt>m < n</
tt>. If <
tt>m</
tt>
is omitted before a dash (<
tt>-</
tt>), the minimum possible integer
is assumed; if <
tt>n</
tt> is omitted after a dash, the maximum
possible integer is assumed.
<
li><
i>Boolean filters</
i>. Used to specify acceptable values for
boolean device attributes. The format of the string is:
<
tt>true|false|yes|no|0|1</
tt>
<
li><
i>Exact match</
i>. Used to specify a single value for the given
device attribute. Any string that doesn't start with <
tt>int:</
tt>
represents the exact match. String device attributes are compared to
this string including case of symbols. Integer attributes are first
converted to a string (see individual filter attributes) and then
<
li><
i>Any match</
i>. Any value of the corresponding device attribute
will match the given filter. An empty or @c null string is
used to construct this type of filtering expressions.
On the Windows host platform, interval filters are not currently
available. Also all string filter attributes
(<
link to="#manufacturer"/>, <
link to="#product"/>,
<
link to="#serialNumber"/>) are ignored, so they behave as
<
i>any match</
i> no matter what string expression is specified.

revision from <

of the USB device physically attached to the host computer regarding
its state on the host computer and availability to guest computers
(all currently running virtual machines).
Once a supported USB device is attached to the host, global USB
filters (<
link to="IHost::USBDeviceFilters"/>) are activated. They can
either ignore the device, or put it to USBDeviceState_Held state, or do
nothing. Unless the device is ignored by global filters, filters of all
currently running guests (<

activated that can put it to USBDeviceState_Captured state.
If the device was ignored by global filters, or didn't match
any filters at all (including guest ones), it is handled by the host
in a normal way. In this case, the device state is determined by
the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
or USBDeviceState_Available, depending on the current device usage.
Besides auto-capturing based on filters, the device can be manually
captured by guests (<

state is USBDeviceState_Busy, USBDeviceState_Available or
Due to differences in USB stack implementations in Linux and Win32,
states USBDeviceState_Busy and USBDeviceState_Unavailable are applicable

///////////////////////////////////////////////////////////////////////// name="ISharedFolder" extends="$unknown" uuid="8388da11-b559-4574-a5b7-2bd7acd5cef8" The ISharedFolder interface represents a folder in the host computer's
file system accessible from the guest OS running inside a virtual
machine using an associated logical name.
There are three types of shared folders:
<
li><
i>Global</
i> (<
link to="IVirtualBox::sharedFolders"/>), shared
folders available to all virtual machines.</
li>
<
li><
i>Permanent</
i> (<
link to="IMachine::sharedFolders"/>),
VM-specific shared folders available to the given virtual machine at
<
li><
i>Transient</
i> (<
link to="IConsole::sharedFolders"/>),
VM-specific shared folders created in the session context (for
example, when the virtual machine is running) and automatically
discarded when the session is closed (the VM is powered off).</
li>
Logical names of shared folders must be unique within the given scope
(global, permanent or transient). However, they do not need to be unique
across scopes. In this case, the definition of the shared folder in a
more specific scope takes precedence over definitions in all other
scopes. The order of precedence is (more specific to more general):
<
li>Transient definitions</
li>
<
li>Permanent definitions</
li>
<
li>Global definitions</
li>
For example, if MyMachine has a shared folder named
<
tt>C_DRIVE</
tt> (that points to <
tt>C:\\</
tt>), then creating a
transient shared folder named <
tt>C_DRIVE</
tt> (that points
to <
tt>C:\\\\WINDOWS</
tt>) will change the definition
of <
tt>C_DRIVE</
tt> in the guest OS so
that <
tt>\\\\VBOXSVR\\C_DRIVE</
tt> will give access
to <
tt>C:\\WINDOWS</
tt> instead of <
tt>C:\\</
tt> on the host
PC. Removing the transient shared folder <
tt>C_DRIVE</
tt> will restore
the previous (permanent) definition of <
tt>C_DRIVE</
tt> that points
to <
tt>C:\\</
tt> if it still exists.
Note that permanent and transient shared folders of different machines
are in different name spaces, so they don't overlap and don't need to
have unique logical names.
Global shared folders are not implemented in the current version of the

name="ISession" extends="$unknown" uuid="12F4DCDB-12B2-4EC1-B7CD-DDD9F6C5BF4D" The ISession interface represents a client process and allows for locking
virtual machines (represented by IMachine objects) to prevent conflicting
Any caller wishing to manipulate a virtual machine needs to create a session
object first, which lives in its own process space. Such session objects are
then associated with <
link to="IMachine" /> objects living in the VirtualBox
server process to coordinate such changes.
There are two typical scenarios in which sessions are used:
<
li>To alter machine settings or control a running virtual machine, one
needs to lock a machine for a given session (client process) by calling
<
link to="IMachine::lockMachine"/>.
Whereas multiple sessions may control a running virtual machine, only
one process can obtain a write lock on the machine to prevent conflicting
changes. A write lock is also needed if a process wants to actually run a
virtual machine in its own context, such as the VirtualBox GUI or
VBoxHeadless front-ends. They must also lock a machine for their own
sessions before they are allowed to power up the virtual machine.
As a result, no machine settings can be altered while another process is
already using it, either because that process is modifying machine settings
or because the machine is running.
To start a VM using one of the existing VirtualBox front-ends (
e.g. the
VirtualBox GUI or VBoxHeadless), one would use
<
link to="IMachine::launchVMProcess"/>, which also takes a session object
as its first parameter. This session then identifies the caller and lets the
caller control the started machine (for example, pause machine execution or
power it down) as well as be notified about machine execution state changes.
How sessions objects are created in a client process depends on whether you use
the Main API via COM or via the webservice:
<
li>When using the COM API directly, an object of the Session class from the
VirtualBox type library needs to be created. In regular COM C++ client code,
this can be done by calling <
tt>createLocalObject()</
tt>, a standard COM API.
This object will then act as a local session object in further calls to open
<
li>In the webservice, the session manager (IWebsessionManager) instead creates
a session object automatically whenever <
link to="IWebsessionManager::logon" />
is called. A managed object reference to that session object can be retrieved by
calling <
link to="IWebsessionManager::getSessionObject" />.

of a storage controller, and for purposes of the Main API, all virtual
storage is attached to virtual machines via instances of this interface.
There are five types of such virtual storage controllers: IDE, SCSI, SATA,
SAS and Floppy (see <

If true, the storage controller emulation will use a dedicated I/O thread, enable the host I/O
caches and use synchronous file APIs on the host. This was the only option in the API before
VirtualBox 3.2 and is still the default for IDE controllers.
If false, the host I/O cache will be disabled for image files attached to this storage controller.
Instead, the storage controller emulation will use asynchronous I/O APIs on the host. This makes

Only within the webservice, a managed object reference (which is really
an opaque number) allows a webservice client to address an object
that lives in the address space of the webservice server.
Behind each managed object reference, there is a COM object that lives
in the webservice server's address space. The COM object is not freed
until the managed object reference is released, either by an explicit
call to <
link to="IManagedObjectRef::release" /> or by logging off from
the webservice (<
link to="IWebsessionManager::logoff" />), which releases
all objects created during the webservice session.
Whenever a method call of the VirtualBox API returns a COM object, the
webservice representation of that method will instead return a
managed object reference, which can then be used to invoke methods

name="IPerformanceCollector" extends="$unknown" uuid="e22e1acb-ac4a-43bb-a31c-17321659b0c6" The IPerformanceCollector interface represents a service that collects
and stores performance metrics data.
Performance metrics are associated with objects of interfaces like IHost
and IMachine. Each object has a distinct set of performance metrics. The
set can be obtained with <
link to="IPerformanceCollector::getMetrics"/>.
Metric data is collected at the specified intervals and is retained
internally. The interval and the number of retained samples can be set
with <
link to="IPerformanceCollector::setupMetrics" />. Both metric data
and collection settings are not persistent, they are discarded as soon as
VBoxSVC process terminates. Moreover, metric settings and data associated
with a particular VM only exist while VM is running. They disappear as
soon as VM shuts down. It is not possible to set up metrics for machines
that are powered off. One needs to start VM first, then set up metric
Metrics are organized hierarchically, with each level separated by a
slash (/) character. Generally, the scheme for metric names is like this:
"
Category/
Metric" together form the base metric name. A base metric is
the smallest unit for which a sampling interval and the number of
retained samples can be set. Only base metrics can be enabled and
disabled. All sub-metrics are collected when their base metric is
collected. Collected values for any set of sub-metrics can be queried
with <
link to="IPerformanceCollector::queryMetricsData" />.
For example "
CPU/
Load/
User:avg" metric name stands for the "CPU"
category, "Load" metric, "User" submetric, "average" aggregate. An
aggregate function is computed over all retained data. Valid aggregate
When setting up metric parameters, querying metric data, enabling or
disabling metrics wildcards can be used in metric names to specify a
subset of metrics. For example, to select all CPU-related metrics
use <
tt>CPU/*</
tt>, all averages can be queried using <
tt>*:avg</
tt> and
so on. To query metric values without aggregates <
tt>*:</
tt> can be used.
The valid names for base metrics are:
The general sequence for collecting and retrieving the metrics is:
Obtain an instance of IPerformanceCollector with
<
link to="IVirtualBox::performanceCollector" />
Allocate and populate an array with references to objects the metrics
will be collected for. Use references to IHost and IMachine objects.
Allocate and populate an array with base metric names the data will
Call <
link to="IPerformanceCollector::setupMetrics" />. From now on
the metric data will be collected and stored.
Wait for the data to get collected.
Allocate and populate an array with references to objects the metric
values will be queried for. You can re-use the object array used for
Allocate and populate an array with metric names the data will be
collected for. Note that metric names differ from base metric names.
Call <
link to="IPerformanceCollector::queryMetricsData" />. The data
that have been collected so far are returned. Note that the values
are still retained internally and data collection continues.
For an example of usage refer to the following files in VirtualBox SDK:

name="IEvent" extends="$unknown" uuid="0ca2adba-8f30-401b-a8cd-fe31dbe839c0" Abstract parent interface for VirtualBox events. Actual events will typically implement
a more specific interface which derives from this (see below).
<
b>Introduction to VirtualBox events</
b>
Generally speaking, an event (represented by this interface) signals that something
happened, while an event listener (see <
link to="IEventListener" />) represents an
entity that is interested in certain events. In order for this to work with
unidirectional protocols (
i.e. web services), the concepts of passive and active
Event consumers can register themselves as listeners, providing an array of
events they are interested in (see <
link to="IEventSource::registerListener" />).
When an event triggers, the listener is notified about the event. The exact
mechanism of the notification depends on whether the listener was registered as
an active or passive listener:
<
li>An active listener is very similar to a callback: it is a function invoked
by the API. As opposed to the callbacks that were used in the API before
VirtualBox 4.0 however, events are now objects with an interface hierarchy.
<
li>Passive listeners are somewhat trickier to implement, but do not require
a client function to be callable, which is not an option with scripting
languages or web service clients. Internally the <
link to="IEventSource" />
implementation maintains an event queue for each passive listener, and
newly arrived events are put in this queue. When the listener calls
<
link to="IEventSource::getEvent"/>, first element from its internal event
queue is returned. When the client completes processing of an event,
the <
link to="IEventSource::eventProcessed" /> function must be called,
acknowledging that the event was processed. It supports implementing
waitable events. On passive listener unregistration, all events from its
queue are auto-acknowledged.
Waitable events are useful in situations where the event generator wants to track
delivery or a party wants to wait until all listeners have completed the event. A
typical example would be a vetoable event (see <
link to="IVetoEvent" />) where a
listeners might veto a certain action, and thus the event producer has to make
sure that all listeners have processed the event and not vetoed before taking
A given event may have both passive and active listeners at the same time.
Any VirtualBox object capable of producing externally visible events provides an
@c eventSource read-only attribute, which is of the type <
link to="IEventSource" />.
This event source object is notified by VirtualBox once something has happened, so
consumers may register event listeners with this event source. To register a listener,
an object implementing the <
link to="IEventListener" /> interface must be provided.
For active listeners, such an object is typically created by the consumer, while for
passive listeners <
link to="IEventSource::createListener" /> should be used. Please
note that a listener created with <
link to="IEventSource::createListener"/> must not be used as an active listener.
Once created, the listener must be registered to listen for the desired events
(see <
link to="IEventSource::registerListener" />), providing an array of
<
link to="VBoxEventType" /> enums. Those elements can either be the individual
event IDs or wildcards matching multiple event IDs.
After registration, the callback's <
link to="IEventListener::handleEvent" /> method is
called automatically when the event is triggered, while passive listeners have to call
<
link to="IEventSource::getEvent" /> and <
link to="IEventSource::eventProcessed" /> in
an event processing loop.
The IEvent interface is an abstract parent interface for all such VirtualBox events
coming in. As a result, the standard use pattern inside <
link to="IEventListener::handleEvent" />
or the event processing loop is to check the <
link to="#type" /> attribute of the event and
then cast to the appropriate specific interface using @c QueryInterface().

If we can wait for this event being processed. If false, <
link to="#waitProcessed"/> returns immediately,
and <

as no additional overhead associated with waitability imposed.
Waitable events are needed when one need to be able to wait for particular event processed,

There are three kinds of runtime errors:
<
li><
i>non-fatal with retry</
i></
li>
<
li><
i>non-fatal warnings</
i></
li>
<
b>Fatal</
b> errors are indicated by the @a fatal parameter set
to @c true. In case of fatal errors, the virtual machine
execution is always paused before calling this notification, and
the notification handler is supposed either to immediately save
the virtual machine state using <
link to="IConsole::saveState"/>
or power it off using <
link to="IConsole::powerDown"/>.
Resuming the execution can lead to unpredictable results.
<
b>Non-fatal</
b> errors and warnings are indicated by the
@a fatal parameter set to @c false. If the virtual machine
is in the Paused state by the time the error notification is
received, it means that the user can <
i>try to resume</
i> the machine
execution after attempting to solve the problem that caused the
error. In this case, the notification handler is supposed
to show an appropriate message to the user (depending on the
value of the @a id parameter) that offers several actions such
as <
i>Retry</
i>, <
i>Save</
i> or <
i>Power Off</
i>. If the user
wants to retry, the notification handler should continue
the machine execution using the <
link to="IConsole::resume"/>
call. If the machine execution is not Paused during this
notification, then it means this notification is a <
i>warning</
i>
(for example, about a fatal condition that can happen very soon);
no immediate action is required from the user, the machine
continues its normal execution.
Note that in either case the notification handler
<
b>must not</
b> perform any action directly on a thread
where this notification is called. Everything it is allowed to
do is to post a message to another thread that will then talk
to the user and take the corresponding action.
Currently, the following error identifiers are known:
<
li><
tt>"HostMemoryLow"</
tt></

requests the console window to be activated and brought to
foreground on the desktop of the host PC.
This notification should cause the VM console process to
perform the requested action as described above. If it is
impossible to do it at a time of this notification, this
method should return a failure.
Note that many modern window managers on many platforms
implement some sort of focus stealing prevention logic, so
that it may be impossible to activate a window without the
help of the currently active application (which is supposedly
an initiator of this notification). In this case, this method
must return a non-zero identifier that represents the
top-level window of the VM console process. The caller, if it
represents a currently active process, is responsible to use
this identifier (in a platform-dependent manner) to perform
actual window activation.
This method must set @a winId to zero if it has performed all
actions necessary to complete the request and the console
window is now active and in foreground, to indicate that no
further action is required on the caller's side.
<
attribute name="winId" type="long long">
