[lxc-users] lxcbr0 doesn't exist after upgrade to 15.10

[Norberto Bensa]

This problem is related to network-manager (NM) or systemd.

I tried to disable NM but I couldn't. NM started with every boot (does
systemd depend on it?). I switched to upstart. Now NM is down, lxcbr0
starts up.

Everything works as it used to be including my routes and dns servers.
