Comment 13 for bug 1824831

Hi Yang,

For QAT, we hardcode alias as you can see the list in your above comment.
For GPU, we also hardcode class_id, name, without vendor_id and product_id, as it may come from different vendors.
In our current design, it do not get GPU info and add it to alias list now.
So, you need specify an alias manually with a system parameter to get a GPU passthrough device, such as
system service-parameter-add nova pci_alias gpu-pf="device_id=0522,vendor_id=8086,name=mygpu"
