Which file exaclty have you put this in? Did you write your own service script and put it in init.d? I've tried this: echo "8086 10b9" > /sys/bus/pci/drivers/pci-stub/new_id echo 0000:01:00.0 > /sys/bus/pci/devices/0000:01:00.0/driver/unbind echo 0000:01:00.0 > /sys/bus/pci/drivers/pci-stub/bind I'll try it again with the fourth line added, manually before I start the VM. How come yours is 'echo "PCI" > /sys/bus/drivers/DRIVERNAME/unbind' and mine is echo "PCI" > /sys/bus/pci/devices/PCI/driver/unbind Obviously one looks up which driver is being used by the PCI id, but how do I look up which driver my PCI card is using?
