Comment 19 for bug 1836682

Hi Matt,

I find another way to pass through SR-IOV capable physical NIC to VM. This new way doesn't require to configure "PCI alias". The key point is to create a port whose vnic_type is direct-physical. The following link can be referenced:
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html/networking_guide/sr-iov-support-for-virtual-networking

However if we try to pass through a physical NIC which doesn't support SR-IOV, we may still need to configure "PCI alias". Because I don't have a physical NIC which doesn't support SR-IOV on my server, I can't test passing such NIC to VM by creating port whose vnic_type is direct-physical.
