215. vhost/virtio-pmd qemu regression test plan

Add feature combind cases to capture regression issue: cover 2 queues + reconnect + multi qemu version + multi-paths with virtio1.0, virtio0.95 and virtio 1.1. For packed virtqueue (virtio 1.1) test, need using qemu version > 4.2.0. The qemu launch parameters (rx_queue_size=1024,tx_queue_size=1024) only can be supported with qemu version greater or equal to 2.10.

215.1. Test flow

TG –> NIC –> Vhost –> Virtio–> Vhost –> NIC –> TG

215.2. Test Case 1: pvp test with virtio 0.95 mergeable path

  1. Bind one port to igb_uio, then launch testpmd by below command:

    rm -rf vhost-net*
    ./testpmd -l 1-3 -n 4 \
    --vdev 'eth_vhost0,iface=vhost-net,queues=2,client=1' -- -i --nb-cores=2 --rxq=2 --txq=2 --txd=1024 --rxd=1024
    testpmd>set fwd mac
    testpmd>start
    
  2. Check dut machine already has installed different version qemu, includes [qemu_2.7, qemu_2.8, qemu_2.9, qemu_2.10, qemu_2.11, qemu_2.12, qemu_3.0], launch VM with different qemu version separately:

    qemu-system-x86_64 -name vm2 -enable-kvm -cpu host -smp 3 -m 4096 \
    -object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on \
    -numa node,memdev=mem -mem-prealloc -drive file=/home/osimg/ubuntu16.img  \
    -chardev socket,path=/tmp/vm2_qga0.sock,server,nowait,id=vm2_qga0 -device virtio-serial \
    -device virtserialport,chardev=vm2_qga0,name=org.qemu.guest_agent.2 -daemonize \
    -monitor unix:/tmp/vm2_monitor.sock,server,nowait -net nic,macaddr=00:00:00:08:e8:aa,addr=1f -net user,hostfwd=tcp:127.0.0.1:6002-:22 \

    -vnc :10
    
  3. On VM, bind virtio net to igb_uio and run testpmd without tx-offloads:

    ./testpmd -c 0x7 -n 4 -- -i --enable-hw-vlan-strip\
    --nb-cores=2 --rxq=2 --txq=2 --txd=1024 --rxd=1024
    testpmd>set fwd mac
    testpmd>start
    
  4. Send 64B and 1518B packets by packet generator separately, show throughput with below command:

    testpmd>show port stats all
    
  5. Quit vhost-user, then re-launch, check if the reconnect can work and ensure the traffic can continue.
