Comprobar si vfio está controlando los dispositivos pasados

Si has pasado dispositivos PCIe a máquinas virtuales de Proxmox y quieres saber si el módulo vfio-pci es el que está efectivamente controlando esos dispositivos (debería), puedes filtrar por el tipo de dispositivo que quieres ver. Para ello sigue este hack:
