Hi Hiteshi, DPDK only detected 1 core, so makes sense that it would reject a coremask of 0xf. I've only tested with QEMU but VirtualBox may only be letting 1 core be emulated - in that case you could try without the --nb-cores flag. However, it would probably affect the performance you will see.
You might find more information on the DPDK mailing list regarding DPDK and VirtualBox, or if not that would probably be the best place to ask as someone may have hit this already and it's not OVS specific. Thanks, Kevin.
