As gibi said above, this is unlikely to be either a nova or a neutron
problem, but more likely a deployment problem. I don't believe the
various neutron log lines quoted have anything to do with the root
cause.

To help with the debugging:

What deployment software did you use?
Are you using devstack - since you said you deployed into vms?
How was the deployment software configured?
Did the deployment complete successfully?
Is neutron-server running?
Is neutron-server actually available at the address nova tries to connect to?
>From both hosts?
Since you mentioned that you used 2 vms, did the error message come from the same host where the controller components are running? If not then the http://localhost:9696/... url is definitely wrong.
