Public bug reported:
After initial upgrade from Ubuntu 15.04 to Ubuntu 15.10 LXC worked for a
couple days then failed. I found that the lxcbr0 interface no longer
existed.
I reported this on the lxc-user alias and about the same time several
others had this happen to them also.
Serge Hallyn requested I open a launchpad bug and post some info but
before I could gather that info the system returned to normal (re lxcbr0
was back) the next day after the server was booted up again.
note: at least one other person had this happen to them also (lxcbr0
came back by itself).
Today, I booted this server again and ... again lxcbr0 was missing where
it had been working last night.
Below is all of the Info Serge Hallyn asked me to post.
$ ifconfig lxcbr0
lxcbr0: error fetching interface information: Device not found
$ journalctl -u lxc-net
