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

[brian mullan]

This problem w/lxcbr0 disappearing has occurred again on my 15.10 server
today.
After boot up lxcbr0 is missing.

I will file a launchpad bug and post the info you requested the last time
this occurred.

I'll also leave the system alone after I file the bug until I hear what
other data you might want me to gather.

But fyi here is the info also:

$* ifconfig lxcbr0*
lxcbr0: error fetching interface information: Device not found


$* journalctl -u lxc-net*
