My trick is to mount cgroup into the container at /lxc/cgroup:

root at vms2:/lxc# grep cgroup flupp.fstab
/cgroup/flupp           /lxc/flupp/lxc/cgroup           none bind,ro 0 0

root at vms2:/lxc# mount | grep cgroup
none on /cgroup type cgroup (rw)

root at vms2:/lxc# lxc-console -n flupp
Type <Ctrl+a q> to exit the console
root at flupp:~# mount | grep cgroup
none on /lxc/cgroup type cgroup (ro,relatime,net_cls,freezer,devices,memory,cpuacct,cpu,ns,cpuset)
