.PCI ID overrides
You can override the PCI vendor ID, device ID, and subsystem IDs that will be
seen by the guest. This is useful if your device is a variant with an ID that
your guest's drivers don't recognize, but you want to force those drivers to be
loaded anyway (e.g. if you know your device shares the same chipset as a
supported variant).
The available options are `vendor-id`, `device-id`, `sub-vendor-id`, and
`sub-device-id`. You can set any or all of these to override your device's
default IDs.
For example:
----
# qm set VMID -hostpci0 02:00,device-id=0x10f6,sub-vendor-id=0x0000
