[libvirt] [PATCH 1/3] Avoid creating top level cgroups if just querying for existance
When getting the driver/domain cgroup it is possible to specify
whether it should be auto created. If auto-creation was turned
off, libvirt still mistakenly created its own top level cgroup
* src/util/cgroup.c: Honour autocreate flag for top level cgroup
