[David Shaughnessy]

I'm submitting this bug as it was advised in the traceback to do so and it does not appear to have been filed yet.

Another log showing the same test failing: http://logs.openstack.org/26/303626/31/check/gate-tempest-dsvm-neutron-multinode-full/f60b580/

For clarity, both of these logs are from a Neutron patch found here: https://review.openstack.org/#/c/303626/

We need something a bit deeper than a stack trace for a bug off of a tempest run like this.
