With an emulated NIC migration is seamless as all configuration for the NIC is within the RAM of the VM and the hypervisor. With a VF you have actual hardware in the picture which needs to be set up properly. I have patch series for that feature. The patches add feature that DPDK apps can attach and detach physical NIC ports and virtual device ports at runtime. Also I have patches for testpmd to attach and detach ports dynamically. For example, after patching, we can type following commands. testpmd> port attach p 0000:02:00.0 testpmd> port attach v eth_pcap0,iface=eth0 testpmd> port detach p testpmd> port detach v (These are just RFC.) Now I am collecting up patches to submit to dpdk.org. So I can send RFC patches soon. Hopefully next week. Thanks, Tetsuya
