Keep the above in your local.conf, and add the following:

Q_PLUGIN=ml2
Q_ML2_PLUGIN_MECHANISM_DRIVERS=openvswitch,logger
Q_AGENT=openvswitch
enable_service q-agt
ENABLE_TENANT_TUNNELS=True

That will enable GRE tunnels between your hosts using your HOST_IP as
the tunnel endpoint. And it should setup floating IPs per the range
you have specified as well.

Thanks.
