The nova stack trace shows that your nova-compute service  cannot
connect to neutron on the URL
http://localhost:9696/v2.0/networks?id=163f0b54-e337-40ac-81af-
958c24ceeb7f . Did you verified that neutron API is available on that
URL?

>From this limited information I suspect that you have a configuration /
deployment issues. I'm setting the nova part of the bug Invalid as it
does not seems to be a nova bug itself.

About the neutron related questions I added the neutron project to the
bug.

** Changed in: nova
       Status: New => Invalid

** Also affects: neutron
   Importance: Undecided
       Status: New
