As Stephen stated this normally something to do with device IDs or NICs not bound to the correct module igb_uio, vfio, …, this I believe is a configuration problem and not a Pktgen problem. The pktgen command line looks correct, but DPDK needs to see the ports before pktgen can use them.

I did not see which kernel module you have attached NICs can you show the dpdk-devbind.py -s output or if you forgot to do that bind inside the VM please bind the NICs to the kernel module you are using. Beyond this little help I do not use VMs very often to get pktgen and not much help here, but as I stated this is not a pktgen problem.

Have you tested other DPDK apps like testpmd/l3fwd/l2fwd and do they work?
