libvirt with lxc: internal error The 'cpuacct', 'devices' & 'memory' cgroups controllers must be mounted

[unicell <unicell@xxxxxxxxx>]

Hi,

I'm running OpenStack to manage LXC instance through libvirt. The same setting runs perfectly well on Ubuntu 12.04, while on CentOS 6u3, libvirt dumped following message when starting lxc instance.

virsh -c lxc:/// start instance-00000032

error: internal error The 'cpuacct', 'devices' & 'memory' cgroups controllers must be mounted

Really appreciated if someone could shed some lights. Seems to some libvirt / cgroup settings related.

$ cat /proc/mounts 

..

none /cgroup cgroup rw,relatime,net_prio,perf_event,blkio,net_cls,freezer,devices,memory,cpuacct,cpu,ns,cpuset 0 0

..

$ chkconfig --list | grep cg

cgconfig        0:off   1:off   2:off   3:off   4:off   5:off   6:off

cgred           0:off   1:off   2:off   3:off   4:off   5:off   6:off

Log message with LIBVIRT_DEBUG=1 if that is helpful.
