      Thanks for your reply! Here is my <a

      <a href="http://paste.openstack.org/show/55035/">neutron.conf</a>.
      Hmm where in neutron.conf I should to configure integration
      bridge?<br>
      I need to install neutron in XenServer too? I run your command
      `ovs-vsctl add-br br-int` and after that tryed to boot instance,
      but same result - fails, with same error message on compute node.<br>

      Hi Mārtiņš,
      <div><br>
      </div>
      <div>It’s definitely possible to have OpenStack Nova and Neutron
        work on XenServer using Open vSwitch. I have it running with ML2
        plugin right now. Can you share your nova.conf and neutron.conf?
        Preferably at
        <a moz-do-not-send="true" href="http://paste.openstack.org">paste.openstack.org</a>
        instead of in an e-mail.</div>
      <div><br>
      </div>
      <div>Also, from your first e-mail message it looks like you are
        missing an integration bridge (where all the instance VIFs plug
        into) in XenServer. Do you have an integration bridge? If so,
        you need to configure it in neutron. If not, try running
        `ovs-vsctl add-br br-int` in XenServer, try booting an instance
        again, and let me know what error message you get.</div>
