Thanks for reporting this bug. I can't seem to reproduce this on my utopic laptop. However, in your example you have > 30 instances running. Do you still get this when you have no instances running when restart cgmanager and libvirtd?
Can you show the following info both before and after the restart/crash: ps -ef | egrep -e '(cgmanager|cgproxy)' cat /proc/self/mountinfo tree /sys/fs/cgroup ** Changed in: libvirt (Ubuntu) Status: New => Incomplete ** Changed in: libvirt (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1397130 Title: libvirt-bin crashes / refuses to restart if cgmanager is restarted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1397130/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
