I have the same problem.

I think this should be address by this branch:

  https://review.openstack.org/86983

The issue stems from the fact that Neutron now tries to make a callback to Nova to notify it that vif plugging has finished... but the default Neutron was incorrect (it didn't have an API version see here https://review.openstack.org/#/c/86646/).

The above two fixes should resolve the confusing error messages.

In order to have Neutron VIF plugging working though you'll need to configure the keystone credentials in Neutron's conf file in order for it to contact Nova.
