I'm assuming you are running on a distro with systemd ?

If so, can you try out this patch

  https://www.redhat.com/archives/libvir-list/2013-September/msg01671.html

It tries to workaround a flaw in either systemd or kernel (we're not
sure which is broken) that causes cgroups to not be cleaned up
