For OVS-DPDK, you need a version above 2.7.0. Below command is used to create a virtio-user port with vhost-kernel backend: # ovs-vsctl add-port br0 virtiouser0 -- set Interface virtiouser0 type=dpdk options:dpdk-devargs=virtio_user0,path=/dev/vhost-net > - How to set the container with the virtio frontend ? No, containers will not hold the virtio frontend in this case. Above ovs-vsctl command will generate a virtio-user port in OVS, and a tap interface in kernel, you can assign the tap interface into a net namespace of some container so that its networking flow will go through OVS-DPDK then to outside.
