I don't see the detection of any of your physical devices here.  I'm guessing
your setup is just looking for ivshmem devices, which you won't have any of in
FC20 unless you rebuild qemu.  As such, dpdk doesn't see any ports, which is why
you're getting the error the results from portid 0 being greater than the number
of detected ports on the system
