You can't monitor bus traffic, you'd still need a PCI analyzer for that, but you can track all driver and guest OS access to the device. So you can at least soft or reverse engineer the driver. To do that, uncomment the #define DEBUG_VFIO line near the top of hw/misc/vfio.c and change all the VFIO_ALLOW_FOO defines from 1 to 0, especially the MMAP one.
