Bug Description
Context:
juju + MAAS deployed OpenStack environment, misc services deployed under LXC on the bootstrap node, interfaces configured for jumbo frames - note that I had to manually set the LXC container interfaces to mtu 9000 before the bridge would do the same.
Action:
Reboot one of the containers; MTU on br0 resets from 9000 -> 1500.
This feels like more of a 'we need a better way to orchestrate MTU configuration across different services' so raising tasks for MAAS and Juju as well.

Hi James,
does setting lxc.network.mtu = 9000 in the container configuration file work?
Depending on how juju creates the containers, you may be able to simply add that line to the bottom of /etc/lxc/ default. conf to get the desired result.
