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

[B G]

After upgrading to 15.10 using LXD, I can't start any of my containers...

lxc start container  -- fails with:

lxc start container-name
error: Error calling 'lxd forkstart neo /var/lib/lxd/containers
/var/log/lxd/container-name/lxc.conf': err='exit status 1'
Try `lxc info --show-log container-name` for more info
root at server2-us:/usr/local# lxc info --show-log neo



When I look at the log - the first line with error goes:

            lxc 1446215170.376 ERROR    lxc_conf -
conf.c:instantiate_veth:2621 - failed to attach 'vethGXCIAF' to the bridge

            lxc 1446215170.406 ERROR    lxc_start -

Appreciate any help here...

I have tried purging lxd and re-installing but doesn't seem to work...
Also the lxc.conf file doesn't seem to exist in the directory from the
error message...
