+        <description>
+          cgroup v2 support has been implemented in libvirt, with both
+          "unified" (v2 only) and "hybrid" (v2 + v1) setups being usable;
+          existing "legacy" (v1 only) setups will keep working.

+          security: Fix permissions for UNIX sockets
+        </summary>
+        <description>
+          Since 4.5.0, libvirt is using FD passing to hand sockets over to
+          QEMU, which in theory removes the need for them to be accessible by
+          the user under which the QEMU process is running; however, other
+          processes such as vdsm need to access the sockets as well, which
+          means adjusting permissions is still necessary.

+        <description>
+          Some storage URIs were not parsed correctly, in which case libvirt
+          ended up emitting XML that it would then refuse to parse back.
