198. vhost/virtio-user smoke test plan

This test plan cover vhost/virtio pvp and loopback topolopy test, split ring and packed ring test, server mode and client mode test, also multi-queues and dynamic queue size test.

198.1. Test Case 1: loopback reconnect test with split ring mergeable path and server mode

  1. Launch vhost as client mode with 2 queues:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xe -n 4 --no-pci --file-prefix=vhost \
    --vdev 'eth_vhost0,iface=vhost-net,client=1,queues=8' -- -i --nb-cores=2 --rxq=2 --txq=2
    >set fwd mac
    >start
    
  2. Launch virtio-user as server mode with 8 queues:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 5-7 --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,server=1,queues=8,mrg_rxbuf=1,in_order=1 \
    -- -i --tx-offloads=0x0 --enable-hw-vlan-strip --rss-ip --nb-cores=2 --rxq=8 --txq=8
    >set fwd mac
    >start tx_first 32
    
  3. Stop vhost port and check queue0 and queue1 RX/TX direction both have packets:

    testpmd>stop
    
  4. Relaunch vhost with 8 queues and send packets:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xe -n 4 --no-pci --file-prefix=vhost \
    --vdev 'eth_vhost0,iface=vhost-net,client=1,queues=8' -- -i --nb-cores=2 --rxq=8 --txq=8
    >set fwd mac
    >start tx_first 32
    stop
    set burst 1
    start tx_first 1
    
  5. Stop vhost port and check queue0 to queue7 RX/TX direction both have packets:

    testpmd>stop
    

198.2. Test Case 2: pvp test with virtio packed ring vectorized path

  1. Bind one port to vfio-pci, then launch vhost by below command:

    rm -rf vhost-net*
    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 2-4 --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1' \
    -- -i --nb-cores=2 --txd=1024 --rxd=1024
    testpmd>set fwd mac
    testpmd>start
    
  2. Launch virtio-user by below command:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 5-6 --no-pci --file-prefix=virtio --force-max-simd-bitwidth=512 \
    --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,packed_vq=1,mrg_rxbuf=0,in_order=1,vectorized=1,queue_size=1024 \
    -- -i --nb-cores=1 --txd=1024 --rxd=1024
    testpmd>set fwd mac
    testpmd>start
    
  3. Send 64B and 1518B packets with packet generator, check the throughput with below command:

    testpmd>show port stats all
