[Bug 1367495] Re: Bridge still not created if bind9 is on

[Yonatan Yehezkeally]

Aha! It was an unprivileged container (I used to get the same error
messages with privileged and unprivileged containers), and it turns out
in one of my purge - install cycles I forgot to add "$USER veth lxcbr0
2" to `/etc/lxc/lxc-usernet`. I did that (it's now the only line there
after the first commented title line), and now I can start the
container! (I rechecked: privileged containers also start.)

In both cases, however, the network is unreachable from within the
container, as evident by the response `connect: Network is unreachable`
to my pinging my host and/or router.  I guess that's not surprising
considerng that `lxc-net` still returns all of these error messages.

However, that's truly a separate issue now, so it's worth summing up
that the uncommented line in `/etc/default/lxc-net` (which was installed
that way, for some reason) was the cause of this bug on my machine. I'm
not sure what to do regarding the new issue (I haven't googled about it
yet), so I'll include what you've asked for just in case you spot an
easy fix. (BTW, I don't know if this belongs on this medium, but you
have my sincere thanks for your help. It was invaluable.)
