The Quantum support with XenServer/XCP was only added in Havana (See http://blogs.citrix.com/2013/06/14/openstack-networking-quantum-on-xenserver-from-notworking-to-networking/).  If you want to use Grizzly then I'd recommend using nova-network.

Having said that, the error below indicates that you cannot connect from your VM with nova-compute through to XAPI.
Check your XENAPI_CONNECTION_URL setting in nova and your host networking configuration.
You should be able to wget a web page from XENAPI_CONNECTION_URL from the DomU that you're running your nova-compute in.
