[Bug 1533833] Re: unprivileged lxc containers won't start

You're using a newer kernel which provides the 'pids' cgroup. Systemd doesn't know about that one and so doesn't create a cgroup for you that you own. Lxc in turn (in wily) doesn't yet know how to handle that. You can work around this several ways. The simplest is to do sudo cgm create pids
