Hi
I am trying to bind Intel X722 NICs, but it is not working in Ubuntu 18.04


*root@hyper02:~# ./dpdk-devbind.py -s*
Network devices using DPDK-compatible driver
============================================
<none>

0000:1c:00.0 'Ethernet Controller 10G X550T' if=eno1 drv=ixgbe

. . . .


*root@hyper02:~# ./dpdk-devbind.py -b vfio-pci 0000:60:00.0 *Error: bind
failed for 0000:60:00.0 - Cannot bind to driver vfio-pci
Error: unbind failed for 0000:60:00.0 - Cannot open
/sys/bus/pci/drivers//unbind

What am I missing?
