hai there. I have tried to build openstack with xenserver. i have two node, first node as a controller (ubuntu 12.04 server) and second node as compute with xenserver as Dom0 and ubuntu 12.04 server as DomU. Status nova compute is up on the dashboard. but i can't create a initial network in controller, i search this problem and found that we can't create initial network because controller and compute is not connected, is the anyone to help me with this ??
