Yeah, given how bad this was for libvirt/qemu I'm surprised I've not seen
this happen in lxc - but I haven't, and noone else has reported it.

open a bug at https://bugs.launchpad.net/ubuntu/+source/lxc/+filebug

OK will do.
Cool, thanks, I'll track it there.
It is a fact that the bridge takes the lowest MAC address from the attached
ports for the host port. See for example
http://backreference.org/2010/07/28/linux-bridge-mac-addresses-and-dynamic-ports/
Thus if a container is restarted, the host port can potentially change its MAC
address and

yes and it does this. The point is that lxcbr0 is not tied to any
physical nic. So the first container you start, however high the
macaddr is, lxcbr0 takes its mac. If the next container gets a
lower macaddr, lxcbr0's macaddr drops.
This lxcbr0 is special to Ubuntu, right? And if not to a
