supportsErrorInfo="no"

wsmap="suppress"

>

<desc>

The IVirtualBoxErrorInfo interface represents extended error information.

Extended error information can be set by VirtualBox components after

unsuccessful or partially successful method invocation. This information

can be retrievefd 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

information.

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 that 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

in the chain).

</desc>

<attribute name="resultCode" type="result" readonly="yes">

<desc>

Result code of the error.

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

by the method that provided this error information, but not

always. For example, on Win32, CoCreateInstance() will most

likely return E_NOINTERFACE upon unsuccessful component

instantiation attempt, but not the value the component factory

returned.

An instance of IVirtualBox is required for the product to do anything

useful. Even though the interface does not expose this, internally,

IVirtualBox is implemented as a singleton and actually lives in the

process of the VirtualBox server (VBoxSVC.exe). This makes sure that

IVirtualBox can track the state of all virtual machines on a particular

<tt>VirtualBox.xml</tt>, is stored.

In this version of VirtualBox, the value of this property is

always <tt>&lt;user_dir&gt;/.VirtualBox</tt> (where

<tt>&lt;user_dir&gt;</tt> is the path to the user directory,

as determined by the host OS), and cannot be changed.

This path is also used as the base to resolve relative paths in

places where relative paths are allowed (unless otherwise

expressly indicated).

</desc>

</attribute>

<attribute name="settingsFilePath" type="wstring" readonly="yes">

<desc>

Full name of the global settings file.

The value of this property corresponds to the value of

<link to="#homeFolder"/> plus <tt>/VirtualBox.xml</tt>.

</desc>

</attribute>

<attribute name="settingsFileVersion" type="wstring" readonly="yes">

<desc>

Current version of the format of the global VirtualBox settings file

(<tt>VirtualBox.xml</tt>).

The version string has the following format:

<pre>

x.y-platform

</pre>

where <tt>x</tt> and <tt>y</tt> are the major and the minor format

versions, and <tt>platform</tt> is the platform identifier.

The current version usually matches the value of the

<link to="#settingsFormatVersion"/> attribute unless the

settings file was created by an older version of VirtualBox and there

was a change of the settings file format since then.

Note that VirtualBox automatically converts settings files from older

versions to the most recent version when reading them (usually at

VirtualBox startup) but it doesn't save the changes back until

you call a method that implicitly saves settings (such as

<link to="#setExtraData()"/>) or call <link to="#saveSettings()"/>

explicitly. Therefore, if the value of this attribute differs from the

value of <link to="#settingsFormatVersion"/>, then it

means that the settings file was converted but the result of the

conversion is not yet saved to disk.

The above feature may be used by interactive front-ends to inform users

about the settings file format change and offer them to explicitly save

all converted settings files (the global and VM-specific ones),

optionally create bacup copies of the old settings files before saving,

etc.

<see>settingsFormatVersion, saveSettingsWithBackup()</see>

<attribute name="settingsFormatVersion" type="wstring" readonly="yes">

<pre>

x.y-platform

</pre>

where <tt>x</tt> and <tt>y</tt> are the major and the minor format

versions, and <tt>platform</tt> is the platform identifier.

VirtualBox uses this version of the format when saving settings files

(either as a result of method calls that require to save settings or as

a result of an explicit call to <link to="#saveSettings()"/>).

<method name="createMachine">

<desc>

Creates a new virtual machine.

The new machine will have "empty" default settings and will not

yet be registered. The typical sequence to create a virtual machine

is therefore something like this:

<ol>

<li>Call this method (IVirtualBox::createMachine) to have a new

machine created. The machine object returned is "mutable", i.e.

automatically locked for the current session, as if

<link to="#openSession" /> had been called on it.</li>

<li>Assign meaningful settings to the new machine by calling the

respective methods.</li>

<li>Call <link to="IMachine::saveSettings" /> to have the settings written

to the machine's XML settings file. The configuration of the newly

created machine will not be saved to disk (and the settings subfolder

and file, as described below, will not be created) until this method

is called.</li>

<li>Call <link to="#registerMachine" /> to have the

machine show up in the list of machines registered with VirtualBox.</li>

</ol>

Every machine has a <i>settings file</i> that is used to store

the machine configuration. This file is stored in the directory

called <i>machine settings subfolder</i>. Unless specified otherwise,

both the subfolder and the settings file will have a name that

corresponds to the name of the virtual machine. You can specify

where to create the machine settings subfolder using the @a

baseFolder argument. The base folder can be absolute (full path)

or relative to the <link to="IVirtualBox::homeFolder">

VirtualBox home directory</link>.

If a null or empty string is given as the base folder (which is

recommended), the <link to="ISystemProperties::defaultMachineFolder">

default machine settings folder</link> will be used as the base

folder to create the machine settings subfolder and file. In

any case, the full path to the settings file will look like:

<pre>

&lt;base_folder&gt;/&lt;machine_name&gt;/&lt;machine_name&gt;.xml

</pre>

Optionally the UUID of the machine can be predefined. If this is

not desired (i.e. a new UUID should be generated), pass just an

empty or null UUID.

You should also specify a valid name for the machine.

See the <link to="IMachine::name"/> property

description for more details about the machine name.

The created machine remains

unregistered until you call <link to="#registerMachine()"/>.

<note>

There is no way to change the name of the settings file or

subfolder of the created machine directly.

<method name="createLegacyMachine">

<desc>

Creates a new virtual machine in "legacy" mode, using the

specified settings file to store machine settings.

As opposed to machines created by <link to="#createMachine()"/>,

the settings file of the machine created in "legacy" mode

is not automatically renamed when the machine name is

changed -- it will always remain the same as specified in this

method call.

The specified settings file name can be absolute

(full path) or relative to the <link to="IVirtualBox::homeFolder">

VirtualBox home directory</link>. If the file name doesn't

contain an extension, the default extension (.xml) will be

appended.

Optionally the UUID of the machine can be predefined. If this is

not desired (i.e. a new UUID should be generated), pass just an

empty or null UUID.

Note that the configuration of the newly created machine is not

saved to disk (and therefore no settings file is created)

until <link to="IMachine::saveSettings()"/> is called. If the

specified settings file already exists,

<link to="IMachine::saveSettings()"/> will return an error.

You should also specify a valid name for the machine.

See the <link to="IMachine::name"/> property

description for more details about the machine name.

The created machine remains

unregistered until you call <link to="#registerMachine()"/>.

@deprecated This method may be removed later. It is better

returned in @a nextKey if the supplied key is the last key. When

supplying @c NULL for the @a key, the first key item is returned in @a

nextKey (if there is any). @a nextValue is an optional parameter and

if supplied, the next key's value is returned in it.

<method name="openSession">

<desc>

Opens a new direct session with the given virtual machine.

Within the direct session context, it is possible to change

all VM settings, as well as to execute the VM in the process

space of the session object. There can be only one direct

session open at a time for every virtual machine. In VirtualBox

terminology, the machine becomes "mutable" after a session has

been opened.

Upon successful return, the session object can be used to

get access to the machine and to the VM console.

Note that the "mutable" machine object, on which you may want

to invoke IMachine methods to change its settings, will be a

different object from the immutable IMachine objects returned

by various IVirtualBox methods. To obtain a mutable

IMachine object, upon which you can invoke settings methods,

use the "machine" attribute of the ISession object which represents

your open session.

In other words, to change settings on a machine, the following

sequence is typically performed:

<ol>

<li>Call this method (openSession) to have a machine locked for

the current session.</li>

<li>Obtain a mutable IMachine object from ISession::machine.</li>

<li>Change the settings of the machine.</li>

</method>

<method name="openRemoteSession">

<desc>

Opens a new remote session with the given virtual machine.

Opening a remote session causes the VirtualBox server to start a new

process that opens a direct session with the given VM. The remote

session provides some level of control over the VM execution to the

caller (using the IConsole interface); however, within the remote

session context, not all VM settings are available for modification.

This operation can take some time (a new VM is started in a new process,

for which memory and other resources need to be set up, which can take

a few seconds). Because of this, a progress object is returned to allow the

caller to wait for this asynchronous operation to be completed. Until then,

the remote session object remains in the closed state and accessing the

machine or its console through it is invalid. It is recommended to use

<link to="IProgress::waitForCompletion" /> or similar calls to wait for

completion.

Currently supported session types (values of the @a type

argument) are:

<ul>

<li><tt>gui</tt>: VirtualBox Qt GUI session</li>

<li><tt>vrdp</tt>: VirtualBox VRDP Server session</li>

</ul>

The @a environment argument is a string containing definitions of

environment variables in the following format:

@code

NAME[=VALUE]\n

NAME[=VALUE]\n

...

@endcode

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, the server environment is

inherited by the started process as is.

<note>

It is an error to open a remote session with the machine

that already has an open direct session or waits until the

previous request to open the remote session is completed

(see <link to="IMachine::sessionState"/>).

The opened @a session will be automatically closed when

the corresponding direct session dies or gets closed.

<method name="waitForPropertyChange">

<desc>

Blocks the caller until any of the properties represented by the @a

what argument changes the value or until the given timeout interval

expires.

The @a what argument is a comma separated list of propertiy masks that

describe properties the caller is interested in. The property mask is

a string in the following format:

@code

[[group.]subgroup.]name

@endcode

where @c name is the property name and @c group, @c subgroup are zero

or or more property group specifiers. Each element (group or name) in

the property mask may be either a latin string or an asterisk symbol

(@c "*") which is used to match any string for the given element. A

property mask that doesn't contain asterisk symbols represents a

single fully qualified property name.

Groups in the fully qualified property name go from more generic (the

left-most part) to more specific (the right-most part). The first

element is usually a name of the object the property belongs to. The

second element may be either a property name, or a child object name,

or an index if the preceeding element names an object which is one of

many objects of the same type. This way, property names form a

hierarchy of properties. Here are some examples of property names:

<table>

<tr>

<td><tt>VirtualBox.version</tt></td>

<td><link to="IVirtualBox::version"/> property</td>

</tr>

<tr>

<td><tt>Machine.&lt;UUID&gt;.name</tt></td>

<td><link to="IMachine::name"/> property of the machine with the

given UUID</td>

</tr>

</table>

Most property names directly correspond to the properties of objects

(components) provided by the VirtualBox library and may be used to

track changes to these properties. However, there may be

pseudo-property names that don't correspond to any existing object's

property directly, as well as there may be object properties that

don't have a corresponding property name that is understood by this

method, and therefore changes to such properties cannot be

tracked. See individual object's property descrcriptions to get a

fully qualified property name that can be used with this method (if

any).

There is a special property mask @c "*" (i.e. a string consisting of a

single asterisk symbol) that can be used to match all properties.

Below are more examples of property masks:

<table>

<tr>

<td><tt>VirtualBox.*</tt></td>

<td>Track all properties of the VirtualBox object</td>

</tr>

<tr>

<td><tt>Machine.*.name</tt></td>

<td>Track changes to the <link to="IMachine::name"/> property of

all registered virtual machines</td>

</tr>

<method name="saveSettings">

<desc>

Saves the global settings to the global settings file

(<link to="#settingsFilePath"/>).

This method is only useful for explicitly saving the global settings

file after it has been auto-converted from the old format to the most

recent format (see <link to="#settingsFileVersion"/> for details).

Normally, the global settings file is implicitly saved when a global

setting is changed.

</desc>

</method>

<method name="saveSettingsWithBackup">

<desc>

Creates a backup copy of the global settings file

(<link to="#settingsFilePath"/>) in case of auto-conversion, and then

calls <link to="#saveSettings()"/>.

Note that the backup copy is created <b>only</b> if the settings file

auto-conversion took place (see <link to="#settingsFileVersion"/> for

details). Otherwise, this call is fully equivalent to

<link to="#saveSettings()"/> and no backup copying is done.

The backup copy is created in the same directory where the original

settings file is located. It is given the following file name:

<pre>

original.xml.x.y-platform.bak

</pre>

where <tt>original.xml</tt> is the original settings file name

(excluding path), and <tt>x.y-platform</tt> is the version of the old

format of the settings file (before auto-conversion).

If the given backup file already exists, this method will try to add the

<tt>.N</tt> suffix to the backup file name (where <tt>N</tt> counts from

0 to 9) and copy it again until it succeeds. If all suffixes are

occupied, or if any other copy error occurs, this method will return a

failure.

If the copy operation succeeds, the @a bakFileName return argument will

receive a full path to the created backup file (for informational

purposes). Note that this will happen even if the subsequent

<link to="#saveSettings()"/> call performed by this method after the

copy operation, fails.

<note>

The VirtualBox API never calls this method. It is intended purely for

the purposes of creating backup copies of the settings files by

front-ends before saving the results of the automatically performed

settings conversion to disk.

<desc>

The IMachine interface represents a virtual machine, or guest, created

in VirtualBox.

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 explicitely stated otherwise in individual attribute

and method descriptions. In order to change a machine setting, a session

for this machine must be opened using one of

<link to="IVirtualBox::openSession"/>,

<link to="IVirtualBox::openRemoteSession"/> or

<link to="IVirtualBox::openExistingSession"/> methdods. After the

session has been successfully opened, 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 ISession interface description for more information

about sessions.

Note that the IMachine interface 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 IConsole

interface. Refer to the IConsole interface description to get more

information about this topic.

<see>ISession, IConsole</see>

</desc>

<attribute name="parent" type="IVirtualBox" readonly="yes">

<desc>Associated parent obect.</desc>

</attribute>

<attribute name="accessible" type="boolean" readonly="yes">

<desc>

Whether this virtual machine is currently accessible or not.

The machine is considered to be inaccessible when:

<ul>

<li>It is a registered virtual machine, and

</li>

<li>Its settings file is inaccessible (for example, it is

located on a network share that is not accessible during

VirtualBox startup, or becomes inaccessible later, or if

the settings file can be read but is invalid).

</li>

</ul>

Otherwise, the value of this property is always <tt>true</tt>.

Every time this property is read, the accessibility state of

this machine is re-evaluated. If the returned value is |false|,

the <link to="#accessError"/> property may be used to get the

detailed error information describing the reason of

inaccessibility.

When the machine is inaccessible, only the following properties

can be used on it:

<ul>

<li><link to="#parent"/></li>

<li><link to="#id"/></li>

<li><link to="#settingsFilePath"/></li>

<li><link to="#accessible"/></li>

<li><link to="#accessError"/></li>

</ul>

An attempt to access any other property or method will return

an error.

The only possible action you can perform on an inaccessible

machine is to unregister it using the

<link to="IVirtualBox::unregisterMachine"/> call (or, to check

for the accessibility state once more by querying this

property).

<note>

In the current implementation, once this property returns

<tt>true</tt>, the machine will never become inaccessible

later, even if its settings file cannot be successfully

read/written any more (at least, until the VirtualBox

server is restarted). This limitation may be removed in

future releases.

</note>

</desc>

</attribute>

<attribute name="accessError" type="IVirtualBoxErrorInfo" readonly="yes">

<desc>

Error information describing the reason of machine

inaccessibility.

Reading this property is only valid after the last call to

<link to="#accessible"/> returned <tt>false</tt> (i.e. the

machine is currently unaccessible). Otherwise, a null

IVirtualBoxErrorInfo object will be returned.

</desc>

</attribute>

<attribute name="name" type="wstring">

<desc>

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

limitations:

<ul>

<li>The machine name cannot be empty.</li>

<li>The machine name can contain only characters that are valid

file name characters according to the rules of the file

system used to store VirtualBox configuration.</li>

<li>You cannot have two or more machines with the same name

if they use the same subdirectory for storing the machine

settings files.</li>

<li>You cannot change the name of the machine if it is running,

or if any file in the directory containing the settings file

is being used by another running machine or by any other

process in the host operating system at a time when

<link to="#saveSettings()"/> is called.

</li>

</ul>

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.

<note>

For "legacy" machines created using the

<link to="IVirtualBox::createLegacyMachine()"/> call,

the above naming limitations do not apply because the

machine name does not affect the settings file name.

The settings file name remains the same as it was specified

during machine creation and never changes.

Current version of the format of the settings file of this machine

The version string has the following format:

<pre>

x.y-platform

</pre>

where <tt>x</tt> and <tt>y</tt> are the major and the minor format

versions, and <tt>platform</tt> is the platform identifier.

The current version usually matches the value of the

<link to="IVirtualBox::settingsFormatVersion"/> attribute unless the

settings file was created by an older version of VirtualBox and there

was a change of the settings file format since then.

Note that VirtualBox automatically converts settings files from older

versions to the most recent version when reading them (usually at

VirtualBox startup) but it doesn't save the changes back until

you call a method that implicitly saves settings (such as

<link to="#setExtraData()"/>) or call <link to="#saveSettings()"/>

explicitly. Therefore, if the value of this attribute differs from the

value of <link to="IVirtualBox::settingsFormatVersion"/>, then it

means that the settings file was converted but the result of the

conversion is not yet saved to disk.

The above feature may be used by interactive front-ends to inform users

about the settings file format change and offer them to explicitly save

all converted settings files (the global and VM-specific ones),

optionally create bacup copies of the old settings files before saving,

etc.
