I am trying to bind an interface eth0 to vfio driver. I have made sure iommu is enabled in grub and kernel. I have loaded the module vfio-pci. Ran following commands
#modprobe vfio-pci #chmod a+x /dev/vfio #chmod 0666 /dev/vfio/* #export DPDK_DIR=/usr/src/dpdk-stable-17.11.4 #sudo $DPDK_DIR/usertools/dpdk-devbind.py --bind=vfio-pci 02:01.0 I got following error: Error: bind failed for 0000:02:01.0 - Cannot bind to driver vfio-pci I checked the error in dmesg: Got : [ 1815.793823] vfio-pci: probe of 0000:02:01.0 failed with error -22 let me know the reason.
