+          lib: autostart objects exactly once
+        </summary>
+        <description>
+          If libvirtd or any of the sub-daemons is started with socket
+          activation then objects might be autostarted more than once.
+          For instance, if a domain under <code> qemu:///session </code>
+          URI is mark as autostarted and the session daemon is started then the
+          domain is started with it. If user shuts the domain down and the
+          session daemon is started again, the user's wish to keep the
+          domain shut off is ignored and the domain is autostarted again.
+          This is now fixed.
