[Bug 1317179] Re: lxc containers fail to start in trusty with newer kernels

[Serge Hallyn]

Now that's odd.  This certainly seemed to be fixed in utopic, but
after a quick dist-upgrade from a trusty host net_cls in fact
does not appear to be there.  So I think you're right - thanks!

 status: confirmed


** Changed in: systemd (Ubuntu)

Title:
  lxc containers fail to start in trusty with newer kernels

Status in “systemd” package in Ubuntu:
  Confirmed
Status in “systemd” source package in Trusty:
  Confirmed

Bug description:
  When running a trusty userspace with a newer kernel (e.g. 3.15-rc4),
  attempting to start a container fails:

  $ lxc-start -n p2
  lxc_container: call to cgmanager_create_sync failed: invalid request
  lxc_container: Failed to create net_cls:p2
  lxc_container: Error creating cgroup net_cls:p2
  lxc_container: failed creating cgroups
  lxc_container: failed to spawn 'p2'

  Iiuc, this seems to be caused new cgroups in the kernel which aren't
  enabled for systemd but that lxc tries to configure anyway.
