Do you have any additional information to add here?  I don’t believe we had to setup an alias in the past to do PCI-PT, so is this something that is new to the latest OpenStack nova release?  Did we drop some functionality to align with upstream nova (that use to be in starlingx-staging)?

Subject: [Starlingx-discuss] [Bug] flavor "pci_passthrough:alias" should be required to passthrough physical NICs

Hi Matt,

Based on my testing, the flavor with property “pci_passthrough:alias” should be required for passing a physical NIC to the VM. But it should not be required for passing a VF to the VM. So I think the alias information should contain physical NICs which are configured with “pci-passthrough” by following command:

system host-if-modify -m 1500 -n pcipass -c pci-passthrough ${COMPUTE} ${IFUUID}

   system interface-datanetwork-assign ${COMPUTE} pcipass ${PHYSNET2}

Could you please let me know your opinions and leave a comment in the below bug:
