<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">Very interesting. I suspect that self._get_vif_ref, below, is returning None. This appears to be when the VM does not exist on the
host - perhaps the VM was renamed, deleted, or it has been migrated to a different host and Nova’s records didn’t get updated?<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">I believe the issue is most likely occurring at

http://git.openstack.org/cgit/<wbr>openstack/nova/tree/nova/virt/<wbr>xenapi/vif.py?h=15.0.4#n246</a> where we attempt to detect the VM based on the instance’s name in Nova’s database.<u></u><u></u></span></p>

state)<u></u><u></u></span></p>
