<listitem><para>List currently running

virtual machines and containers.

</para></listitem>

</varlistentry>

<varlistentry>

<term><command>status</command> <replaceable>NAME</replaceable>...</term>

<listitem><para>Show terse runtime

status information about one or more

virtual machines and containers. This

function is intended to generate

human-readable output. If you are

looking for computer-parsable output,

use <command>show</command> instead.

</para></listitem>

</varlistentry>

<varlistentry>

<term><command>show</command> <replaceable>NAME</replaceable>...</term>

<listitem><para>Show properties of one

or more registered virtual machines or

containers or the manager itself. If

no argument is specified, properties

of the manager will be shown. If an

NAME is specified, properties of this

virtual machine or container are

shown. By default, empty properties

are suppressed. Use

<option>--all</option> to show those

too. To select specific properties to

show, use

<option>--property=</option>. This

command is intended to be used

whenever computer-parsable output is

required. Use

<command>status</command> if you are

looking for formatted human-readable

output.</para></listitem>

</varlistentry>

<varlistentry>

<term><command>login</command> <replaceable>NAME</replaceable></term>

<listitem><para>Open a terminal login

session to a container. This will

create a TTY connection to a specific

container and asks for the execution of a

getty on it. Note that this is only

supported for containers running

<citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>

as init system.</para></listitem>

</varlistentry>

<varlistentry>

<term><command>reboot</command> <replaceable>NAME</replaceable>...</term>

<listitem><para>Reboot one or more

containers. This will trigger a reboot

by sending SIGINT to the container's

init process, which is roughly

equivalent to pressing Ctrl+Alt+Del on

a non-containerized system, and is

compatible with containers running any

init system.</para></listitem>

</varlistentry>

<varlistentry>

<term><command>poweroff</command> <replaceable>NAME</replaceable>...</term>

<listitem><para>Power off one or more

containers. This will trigger a reboot

by sending SIGRTMIN+4 to the

container's init process, which causes

systemd-compatible init systems to

shut down cleanly. This operation does

not work on containers that do not run

a

<citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>-compatible

init system, such as

sysvinit.</para></listitem>

</varlistentry>

<varlistentry>

<term><command>kill</command> <replaceable>NAME</replaceable>...</term>

<listitem><para>Send a signal to one

or more processes of the virtual

machine or container. This means

processes as seen by the host, not the

processes inside the virtual machine

or container.

Use <option>--kill-who=</option> to

select which process to kill. Use

<option>--signal=</option> to select

the signal to send.</para></listitem>

</varlistentry>

<varlistentry>

<term><command>terminate</command> <replaceable>NAME</replaceable>...</term>

<listitem><para>Terminates a virtual

resources attached to that

instance.</para></listitem>

<varlistentry>

<term><command>bind</command> <replaceable>NAME</replaceable> <replaceable>PATH</replaceable> [<replaceable>PATH</replaceable>]</term>

<listitem><para>Bind mounts a

directory from the host into the

specified container. The first

directory argument is the source

directory on the host, the second

directory argument the source

directory on the host. When the latter

is omitted the destination path in the

container is the same as the source

path on the host. When combined with

the <option>--read-only</option>

switch a ready-only bind mount is

created. When combined with the

<option>--mkdir</option> switch the

destination path is first created

before the mount is applied. Note that

this option is currently only

supported for

name, followed by the source path on

the host and the destination path in

the container. If the destination path

is omitted the same as the source path
