AFAIW, libvirt requires "device" subsystem of cgroups as well. Without it, an assistant subprocess of libvirtd will die soon.
So rishi, could add a devices line as well to the cgconfig configuratoin file, and test it out?
Cool !!! I am able to run container, once mounted "device" susbsystem too. Thanks Ryota.

So, Are we fixing the flow of libvirt & cgroup start mechanism ? Because user need not have to stop "libvirtd" , if he wants to use cgroup ?
We can certainly improve that - can you file a bug against libvirt with this info Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
