(applogies for previous encrypted email, enigmail somehow flagged
openstack-dev as encrypt by default for me.)

... Right, remember that getting a working neutron config requires a raft of
variables set correctly in the first place. Also, unlike n-net (which
owns setting up it's own network), neutron doesn't bootstrap it's own
bridges. Devstack has to specifically do ovs commands to create the
bridges for neutron otherwise it face plants. I expect that in this case
we're missing all that extra devstack initialization here, based on what
I saw in the failures.
