<p>
libvirt-dbus wraps libvirt API to provide a high-level object-oriented
API better suited for dbus-based applications.
</p>
<h2>
<a name="git">GIT source repository</a>
</h2>
<p>
The D-Bus bindings source code is maintained in a
<a href="https://git-scm.com/">git</a> repository available on
<a href="https://libvirt.org/git/">libvirt.org</a>:
</p>
<pre>
git clone https://libvirt.org/git/libvirt-dbus.git
</pre>
<p>
They can also be browsed online:

<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>.
</p>
<p>
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:
</p>
<pre>
<?xml version="1.0"?>
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN"
"http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
<busconfig>
<policy user="foo">
<allow send_destination="org.libvirt"/>
</policy>
</busconfig>
</pre>
<p>
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
