Thanks Christian https://help.ubuntu.com/16.04/serverguide/DPDK.html#dpdk-openvswitch-guest is out of order. Can you please suggest any other link.

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<mailto: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. For this I have done the followings- 1. Binded eth0 and eth1 of host machine to DPDK 2. Created the OVS bridge in host machine as below $OVS_DIR/utilities/ovs-vsctl add-br ovsbr0 -- set Bridge ovsbr0 datapath_type=netdev $OVS_DIR/utilities/ovs-vsctl add-port ovsbr0 dpdk0 -- set Interface dpdk0 type=dpdk $OVS_DIR/utilities/ovs-vsctl add-port ovsbr0 dpdk1 -- set Interface dpdk1 type=dpdk 3. Installed the VM and created virtual NIC(eth4, eth5) 4. Binded VM machine NIC to VM's DPDK Now I am not able to understand how to attach VM's NIC to OVS? To solve this I tried below command on HOST MACHINE $OVS_DIR/utilities/ovs-vsctl add-port ovsbr0 dpdk4 -- set Interface dpdk4 type=dpdk $OVS_DIR/utilities/ovs-vsctl add-port ovsbr0 dpdk5 -- set Interface dpdk5 type=dpdk but got error "Cannot get interface dpdk4". I believe this is due to OVS is looking in host machine for interface "dpdk4 & dpdk5" although these interface are available in VM machine. Do I need QEMU, if yes then how it will help. Please suggest.
