Ok, if you look at the source, that message is a bit misleading - lxc never got around to trying to move the task into the cgroup, it failed to load a suitable set of cgroups data in the first place. You really should be using cfsng, not cgfs. Can you show your cgroup layout? (cat /proc/self/cgroup and mount | grep cgroup) It might help if you set the lxc.cgroup.use in your personal lxc.system.conf (~/.config/lxc/lxc.conf) to only include the cgroups your container needs - just freezer is the bare minimum. That might get your container running without switching to cgfsng. -serge _______________________________________________ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
