<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>
<br>
I am trying to use Openstack Grizzly to control XCP hypervisor with quantum ovs plugin. I tried with the steps which are mentioned in official document (<a href="http://docs.openstack.org/grizzly/openstack-compute/install/apt/content/introduction-to-xen.html#xen-config-reference" target="_blank">http://docs.openstack.org/<u></u>grizzly/openstack-compute/<u></u>install/apt/content/<u></u>introduction-to-xen.html#xen-<u></u>config-reference</a>) but it doesn't work for me. I am not able to start nova-compute service. It is giving me following error:<br>

It seems network with openvswitch is not configured properly. Is there any OVS quantum plugin requires to run under dom0? Is there any document which can briefly describe how Openstack + XCP works with OVS Quantum?<br>
