Hi All, I am testing ovs-dpdk performance test with the help of IPERF. I created VM using qemu command. I assigned IP 10.0.1.16 to VM and other device IP is 10.0.1.18 (Dev2). I am able to ping and able to run IPERF. It is giving average output ~3.5G form VM to DEV2 on 10G physical interface. form DEV2 to VM it is 5.7G throughput.
I used below version. DPDK: dpdk-18.11.1.tar.xz OVS: openvswitch-2.11.1 >From Intel document I found TSO changes but it was for 2.6 version. somehow I >managed to apply on openvswitch-2.11.1 file. With TSO disable I am able to do ssh other IP address of DEV2. After enable TSO with the help of qemu command IPERF and SSH is getting hanged. https://mail.openvswitch.org/pipermail/ovs-dev/2018-August/350834.html Is openvswitch-2.11.1 supports TSO enable by default? Is any patch availble for openvswitch-2.11.1 for TSO changes? Is qemu related changes are required for TSO enable? I used below changes using qemu command. csum=on,gso=on,host_tso4=on,host_tso6=on,host_ecn=on,host_ufo=on,guest_tso4=on,guest_csum=on,guest_tso6=on,guest_ecn=on,guest_ufo=on Thaks lot. Regards Murali
