Comment 12 for bug 1824831

GPU device is missing "vendor_id" and "product_id" in the alias, so nova instance ended up with a device from a random passthrough device, in my case, on a compute host with both Crypto and GPU devices, even though the nova flavor specifies "pci_passthrough:alias"="gpu:1", eventually the Crypto VF got used.

My expectation is the whole gpu pf should have been passed to nova instance.

# Here are the devices on the compute:
