Get PCI Address (e.g., 0000:00:02.0)

lspci -nn | grep Ethernet

Unbind from kernel driver (e1000)

you will lose connectivity from that interface on running the command

echo "0000:00:02.0" > /sys/bus/pci/devices/0000:00:02.0/driver/unbind

Bind to vfio-pci

$ lspci -n -s 0000:00:02.0 00:02.0 0200: 8086:100e (rev 03) $ echo 8086 100e > /sys/bus/pci/drivers/vfio-pci/new_id
