Description
|
|
-----------
|
|
|
|
libvirt-dbus wraps libvirt API to provide a high-level object-oriented API
|
|
better suited for dbus-based applications.
|
|
|
|
GIT source repository
|
|
---------------------
|
|
|
|
The D-Bus bindings source code is maintained in a `git <https://git-scm.com/>`__
|
|
repository available on
|
|
`gitlab.com <https://gitlab.com/libvirt/libvirt-dbus>`__:

Usage
|
|
-----
|
|
|
|
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).
|
|
|
|
The name of the libvirt-dbus service is ``org.libvirt``. libvirt-dbus
|
|
distributes an interface XML descriptions which can be usually found at
|
|
``/usr/share/dbus-1/interfaces/``.
|
|
|
|
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 ``/etc/dbus-1/system.d/org.libvirt.conf`` that contains:
|
|
|
|
::
|
|
|
|
<?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>
|
|
|
|
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):
|
|
|
|
::
|
|
|
|
gdbus introspect --xml --session --dest org.libvirt --object-path /org/libvirt
|
|
gdbus introspect --xml --system --dest org.libvirt --object-path /org/libvirt
|
|
|
|
Every object is introspectable so you can get a list of available interfaces
|
|
with methods, signals and properties running this command:
|
|
|
|
::
|
|
|
|
gdbus introspect --xml --system --dest org.libvirt --object-path /org/libvirt/QEMU
|
|
|
|
To get a list of domains for specific connection driver you can run this
|
|
command:
|
|
|
|
::
|
|
|
|
gdbus call --system --dest org.libvirt --object-path /org/libvirt/QEMU \
|
|
--method org.libvirt.Connect.ListDomains 0
