I ran into a similar issue, and with Kyle's help, was able to fix it. In the repo Kyle mentioned, there's a file lib/nova. You want to add the following patch
to that file:
Once I did this, I was able to run stack.sh successfully.

Is this a fresh Ubuntu/Fedora box? Do you have a firewall
enabled? Looks like your credentials are wrong. Make sure
you have updated the IP addresses in the localrc file before

> After returning from the OpenStack Summit in Hong Kong last week, I've spent some time working on the Neutron ML2 MechanismDriver for ODL. The good news is that after plenty of help from Ryan Moats, I've got it working now! Instructions on how to use it are
below. The next steps are to integrate this with something which plugs into the NeutronAPIService APIs I'm using in ODL now. For the OVSDB integration efforts there, we will also require some possible API calls to alert ODL about hosts as the come online.
