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 user sudo cgm chown pids user $(id -u) $(id -g) cgm movepid pids user $$ before you start the container. ** Also affects: systemd (Ubuntu) Importance: Undecided Status: New ** Changed in: lxc (Ubuntu) Importance: Undecided => Medium ** Changed in: lxc (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1533833 Title: unprivileged lxc containers won't start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1533833/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
