<p class="MsoNormal"><span lang="EN-CA">The latest openstack release should support using the port vnic_type for type-PCI devices. The only device I know of that doesn’t support PF/VF is the i210, which is what I think was used in reporting the bug. I think
your approach of having them retest with this method is the correct thing to do given you don’t have access to the hardware.<o:p></o:p></span></p>
