Title:
  Host veth mtu not preserved during container reboot

Status in lxc package in Ubuntu:
  New

Bug description:
  LXC containers configured with lxc.network.mtu = 9000

  On start/restart using lxc-* commands, the mtu on the host and in
  container interface is correctly set to 9000.

  However, if the container is rebooted internally, the mtu of the veth
  on the host resets to 1500, whilst the container interface is still
  set to 9000.

  This causes some odd network behaviour.
