Just to be sure, can you show the systemd version you were using here? The intent was to check with systemd from wily-proposed, with the regular wily kernel. In particular, an upstream kernel would be expected to fail by default without setting an extra apparmor flag in the container configuration (though that doesn't seem to be how yours is failing)
What does /proc/self/cgroup look like? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1533833 Title: unprivileged lxc containers won't start, need to put sessions into "pids" cgroup controller Status in lxc package in Ubuntu: Fix Released Status in systemd package in Ubuntu: Fix Released Status in lxc source package in Wily: New Status in systemd source package in Wily: Fix Committed Bug description: I'n trying to get (unpriviliged) lxc containers to run on wily.
