We have developed virtio-user + vhost-kernel as the backend. In that
scenario, you can add the tap interface into a container network namespace.
And there's a vhost kthread to push the data out to user space.
And I cannot guarantee the performance as it has diametric model in VM
(virtio) - OVS-DPDK (vhost).

Can you refer to a document how to run this setup?
Please refer to

I've tested the performance of a container connected to OVS-DPDK via
vdev-af_packet and processed by virtual PMD, and its performance is
good [uses mmap'ed to userspace - zero copy RX/TX ring buffer] but
not good as the performance of a VM connected to OVS-DPDK (@host)
via vhost-user virtio.

Hello,
Does anyone know the status of this project
