[libvirt] How to deal with LXC cgroup access control with apparmor ?

I don't know if it “legal” to send the email here ：）
I am playing with libvirt 1.1.1 (lxc)
when I was starting a LXC container, the process location of cgroup is pretty , just the root directory
from the process. But I could tune the cgroup in a container as an user that logged, This is not accepted...
I wonder how to restrict it with apparmor ,so one can not modify files in the cgroup fs, e.g the cpus or mem,
if i restrict it with "deny /sys/fs/cgroup/** wrklx," in apparmor ,the container woulld not start up .
"Permission denied", because that a process would mount the cgroup, it seems done by libvirt_lxc,
Any way to restrict the cgroup in the container or just not mount cgroup in the container ??
Any help would be appreciated, thanks .
