[Greg Chavez <greg.chavez@xxxxxxxxx>]

Thanks, Unmesh.  My nova.conf on my compute node had some conflicting
settings.  E.g. I am using quantum, but I still had network_manager =
nova.network.manager.FlatDHCPManager.

That error is gone.  But naturally I have new ones now.  I'll start a new
thread for that :)
