You wouldn't be able to call ifconfig on your VF device if you have bound your guest VF device to igb_uio driver. Have you bound your VF device to igb_uio? Or you have enabled automatic port unbinding (which is disabled by default in recent releases)?

Are you referring to two different VM's each having a separate VF device, or are you trying to run two primary processes on one VM with different VF devices?
