Public bug reported:

As per the documentation shown below

https://docs.openstack.org/nova/pike/admin/pci-passthrough.html

In order to achieve PCI passthrough of a network device, it states that
we should create a 'flavor' based on the alias and then associate a
flavor to the server create function.

Steps to follow:

Create an Alias:
[pci]
alias = { "vendor_id":"8086", "product_id":"154d", "device_type":"type-PF", "name":"a1" }

Create a Flavor:
[pci]
alias = { "vendor_id":"8086", "product_id":"154d", "device_type":"type-PF", "name":"a1" }

Add a whitelist:
[pci]
passthrough_whitelist = { "address": "0000:41:00.0" }

Create a Server with the Flavor:

# openstack server create --flavor m1.large --image
cirros-0.3.5-x86_64-uec --wait test-pci


With the above command, the VM creation errors out and we see a PortBindingFailure.

The reason for the PortBindingFailure is the 'vif_type' is always set to
'BINDING_FAILED".

The reason being, flavor does not mention about the 'vnic_type'='direct-
physical' without this information the sriov mechanism driver is not
able to bind the port.

Not sure if there is any way to specify the info in the flavor.
