Your kernel does not have the apparmor patchset to support mount
restrictions.  So long as tha tis the case, your workaround is the
correct one.  Note that (privileged) containers are less secure this
way, although unprivileged containers should be ok.

Title:
  lxc-start fails due to insufficient permission for creating netdev

Status in lxc package in Ubuntu:
  Invalid

Bug description:
  After installing an lxc with `sudo lxc-create -n Ubuntu-12.04.5-i386
  -t /usr/share/lxc/templates/lxc-ubuntu -- --release precise --mirror
  http://richtercloud.de:3142/de.archive.ubuntu.com/ubuntu --arch i386`,
  starting the container with `sudo lxc-start -n Ubuntu-12.04.5-i386
  --foreground` fails due to the following error:

      lxc-start: conf.c: instanciate_veth: 2817 failed to attach 'vethY1J1I1' to the bridge 'lxcbr0' : Operation not permitted
      lxc-start: conf.c: lxc_create_network: 3100 failed to create netdev
      lxc-start: start.c: lxc_spawn: 829 failed to create the network
      lxc-start: start.c: __lxc_start: 1087 failed to spawn 'Ubuntu-12.04.5-i386'
      lxc-start: lxc_start.c: main: 337 The container failed to start.
      lxc-start: lxc_start.c: main: 341 Additional information can be obtained by setting the --logfile and --logpriority options.

  It should be possible to start the container right away after
  installation of the apt package and handle eventually necessary setup
  tasks (of permissions, etc.) in `debconf`.

  Currently it's necessary to comment out all `lxc.network.*` entries in
  the container configuration file.
