Avi: You have got to some level with a virtio-user interface, in the backend, it does allow OVS-DPDK (or VPP, but not tested) talked to the container guest with the virtio interface,
There was a proposal to merge that interface to VPP community. But it does not fly much with the memif context, the mail archive is moving to the new place, the google search cannot help me to identify the mail thread yet. The performance will be similar as the OVS-DPDK for the container use case.

Another option is to connect with veth pair - but the performance is further degraded Another issue is how VPP interface with sandbox?
