Comment 9 for bug 1690345

lxdbr0 is not used by the nova-lxd driver (it wires things into Neutron, rather than into anything LXD itself controls) so I'd not expect that to fix anything.

Thing that would help debug this include:

   sudo lxc profile show <name>
   sudo ovs-vsctl show
   sudo ip link

That will give me a little visibility into what's not happening.
