Can you open a launchpad bug and describe there the system you upgraded
from?  (i.e. was it stock 14.04 with systemd?  desktop, with network-manager?
/etc/network/interfaces contents;  and what do you get when you run

journalctl -u lxc-net
/usr/lib/x86_64-linux-gnu/lxc/lxc-net stop
/usr/lib/x86_64-linux-gnu/lxc/lxc-net start
