LXD v2.0.0-rc8 does not work with Juju v2.0-beta3

[roger peppe]

To add to this conversation, I have encountered this issue today
and have been unable to resolve it so far in the limited time
I've been able to spend on it.

I'm running on Trusty; I have the new version of lxd and the
latest version of Juju tip.

In my case, the issue seems to be that my lcdbr0 interface
has no IPv4 addresses (I've tried fiddling with /etc/default/lxd-bridge
and restarting various things to avail) and that the
utils.GetAddressForInterface
function excludes all IPv4 addresses. I'm thinking that it shouldn't do that,
but that might not be the only thing that's wrong.
