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.
