Re: [ovs-discuss] Intro to OpenVSwitch

Hi, I don't know about Libvirt/OVS, but this seems like something that should be possible with virsh/iptables. Did you try something like this? https://aboullaite.me/kvm-qemo-forward-ports-with-iptables/ Maybe the Libvirt mailing list can help. > -Original Message- > From:

Maybe you need to set the pmd-cpu-mask. I don't know what it defaults to. I think this will place a PMD on the fourth core ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0x8 Then make sure ovs-vswitchd is stopped and try starting it like step 5 in

Re: [ovs-discuss] OVS-DPDK performance problem in Openstack Ocata

Yes that test gives much better results without DPDK - I saw 18Gbps. The reason is that OVS-DPDK does not support TSO. But DPDK does better with UDP and packets/second tests. Some patches were proposed - google ovs dpdk tso. You could try using more queues -
