+D-Bus display
+=============
+
+QEMU can export the VM display through D-Bus (when started with ``-display
+dbus``), to allow out-of-process UIs, remote protocol servers or other
+interactive display usages.
+
+Various specialized D-Bus interfaces are available on different object paths
+under ``/org/qemu/Display1/``, depending on the VM configuration.
+
+QEMU also implements the standard interfaces, such as
+`org.freedesktop.DBus.Introspectable
+<https://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces>`_.
