-VTN doesn't seem to like cloudlab's networks (flat-net-1, ext-net, etc). You might have to delete them all.
+VTN doesn't seem to like cloudlab's networks (flat-net-1, ext-net, etc). You might have to delete them all. I've placed a script in xos/scripts/ called destroy-all-networks.sh that will automate tearing down all of cloudlab's neutron networks.
For development, I suggest using the bash configuration (remember to start the ONOS observer manually) so that
there aren't a bunch of preexisting Neutron networks and nova instances to get in the way.
