<p>
|
|
libvirt-dbus wraps libvirt API to provide a high-level object-oriented
|
|
API better suited for dbus-based applications.

The D-Bus bindings source code is maintained in a

<a href="https://git-scm.com/">git</a> repository available on

<p>
|
|
libvirt-dbus exports libvirt API using D-Bus objects with methods and
|
|
properties described by interfaces. Currently only local connection
|
|
to libvirt is exported and the list of supported drivers depends
|
|
on the type of the bus connection (session or system).
|
|
</p>
|
|
|
|
<p>
|
|
The name of the libvirt-dbus service is <code>org.libvirt</code>.
|
|
libvirt-dbus distributes an interface XML descriptions which can be
|
|
usually found at <code>/usr/share/dbus-1/interfaces/</code>.

|
By default unprivileged user has access only to the session D-Bus
|
|
connection. In order to allow specific user "foo" to access the system
|
|
D-Bus connection you need to create a file
|
|
<code>/etc/dbus-1/system.d/org.libvirt.conf</code> that contains:

To get a list of supported drivers for the specific bus connection
|
|
you can run these commands (not all drivers may be available on
|
|
the host):
|
|
</p>
|
|
|
|
<pre>
|
|
gdbus introspect --xml --session --dest org.libvirt --object-path /org/libvirt
|
|
gdbus introspect --xml --system --dest org.libvirt --object-path /org/libvirt
|
|
</pre>
|
|
|
|
<p>
|
|
Every object is introspectable so you can get a list of available
|
|
interfaces with methods, signals and properties running this command:
|
|
</p>
|
|
|
|
<pre>
|
|
gdbus introspect --xml --system --dest org.libvirt --object-path /org/libvirt/QEMU
|
|
</pre>
|
|
|
|
<p>
|
|
To get a list of domains for specific connection driver you can run
|
|
this command:
|
|
</p>
|
|
|
|
<pre>
|
|
gdbus call --system --dest org.libvirt --object-path /org/libvirt/QEMU \
|
|
--method org.libvirt.Connect.ListDomains 0
