99. perf vm2vm vhost-user/virtio-net test plan

99.1. Description

This test plan test vhost tx offload (TSO) function by verifing the TSO/cksum in the TCP/IP stack enabled environment with vm2vm split ring and packed ring vhost-user/virtio-net mergeable path. For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1.

99.2. Test flow

Virtio-net <-> Vhost <-> Testpmd <-> Vhost <-> Virtio-net

99.3. Test Case 1: Perf VM2VM split ring vhost-user/virtio-net test with tcp traffic

  1. Launch the Vhost sample by below commands:

    rm -rf vhost-net*
    ./testpmd -l 2-4 -n 4 --no-pci --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net0,queues=1' \
    --vdev 'net_vhost1,iface=vhost-net1,queues=1'  -- -i --nb-cores=2 --txd=1024 --rxd=1024
    testpmd>start
    
  2. Launch VM1 and VM2:

    taskset -c 13 qemu-system-x86_64 -name vm1 -enable-kvm -cpu host -smp 1 -m 4096 \
    -object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on \
