Comment 30 for bug 1836682

Hi Matt,

I have finished my testing with I210 NIC and the result shows that this way should be only used for SR-IOV physical function. And the blueprint "SR-IOV physical functions assignment with Neutron port" also indicates the same thing.
https://blueprints.launchpad.net/nova/+spec/sriov-pf-passthrough-neutron-port

For this limitation, which way do you suggest?
1. Record as a known limitation and document how to pass through NICs which don't support SR-IOV. Like below: users need to override helm with PCI alias like following:
 cat > nova-overrides.yaml <<EOF
   conf:
   nova:
     DEFAULT:
       debug: True
     pci:
       alias:
           type: multistring
           values:
           - '{"vendor_id": "8086", "product_id": "37d2","device_type":"type-PCI","name": "pci-pass"}'
   EOF
  system helm-override-update stx-openstack nova openstack --values nova-overrides.yaml

2. Generate the helm override automatically. If this way is chosen, do you think this should be fixed in stx 2.0 or stx 3.0?
