Hi Vivek, you are right the dpdk4/5 would be adding more Host interfaces to the bridge. IMHO your steps 3&4 make wrong assumptions how this should work.
You want to create virtual interfaces on the Host that can be consumed by your guest. These days you use vhost_user sockets for that. Create one in the Host with e.g. with: ovs-vsctl add-port ovsdpdkbr0 vhost-user-1 -- set Interface vhost-user-1 type=dpdkvhostuser You then need to configure your guest in a way to configure its vnic to attach to that socket. That can be done with qemu commandline or some assist by recent libvirt. You might take a look at the examples here: https://help.ubuntu.com/16.04/serverguide/DPDK.html#dpdk-openvswitch-guest or more complete, but then also more complex https://github.com/openvswitch/ovs/blob/master/INSTALL.DPDK.md#dpdk-vhost-user-vm-configuration Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd On Wed, Apr 27, 2016 at 3:53 PM, Vivek Gupta <vive...@hcl.com> wrote: > Hi All > > I am testing a scenario where I will receive the traffic on DPDK binded > port on host machine and will forward that traffic to DPDK binded port of > VM machine.
