For my issue, I found a workaround by manually creating /dev/uio0 using mknod. But I still get the vfio error. If I try "sudo modprobe vfio" but that gives an error that Module vfio not found. I tried looking for vfio.ko in the dpdk source tree as well but could not find that module. How can I install the vfio module? Thanks!

VFIO is supplied by kernel :) if you use uio then vfio can be ignored. It is just another way of things in new kernel(version > 3.6).
