thanks for filing this bug. lxc-ls actually handles the case where mount -t cgroup shows nothing, by then checking in /proc/self/mounts.
The /sys/fs/cgroup/<subsys>/<init-cgroup>/lxc directory is explicitly created with 0755. The container's directory (mistakenly) is not, i.e. /sys/fs/cgroup/<subsys>/<init-cgroup>/lxc/container1. But your output isn't showing that, it's showing lxc itself. Curious! Can you tell us what else you have installed? dpkg -l | grep libvirt dpkg -l | grep cgroup and how long it has been running? ** Changed in: lxc (Ubuntu) Status: New => Confirmed ** Changed in: lxc (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/925110 Title: lxc-ls fails as non-root sometimes (second bug) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/925110/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
