    I was previously using Proxmox 6.1 and passing through my RX480 to a windows guest.

    [Script/Service] - Passthrough Helper

    Hi, i've camed in another thread to the Problem, that there is no easy way to bind vfio-pci to a bus device. This is neccessary if you can't do it with vendor:device id, because you have multiple devices and you need them on your host too. For example, if you want to passthrough one of four nic...
