243. vhost/virtio different qemu version test plan

243.1. Description

This test plan will test pvp different qemu version test cases, also cover virtio 0.95, virtio 1.0 and virtio 1.1.

243.2. Test flow

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

243.3. Test Case 1: PVP multi qemu version test with virtio 0.95 mergeable path

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

   rm -rf vhost-net*
   ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xe -n 4 \
   --vdev 'eth_vhost0,iface=vhost-net,queues=1' -- \
   -i --nb-cores=1 --txd=1024 --rxd=1024
   testpmd>set fwd mac
   testpmd>start
   

2. Check dut machine already has installed different version qemu, includes [qemu-5.2.0, qemu-6.2.0, qemu-7.0.0, qemu-7.1.0, qemu-7.2.0].

3. Go to the absolute_path of different version qemu,then launch VM with different version qemu, note: we need add “disable-modern=true” to enable virtio 0.95:

   qemu-system-x86_64 -name vm2 -enable-kvm -cpu host -smp 2 -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 \
   -netdev user,id=netdev0,hostfwd=tcp:127.0.0.1:6002-:22 \
   -chardev socket,id=char0,path=./vhost-net \
   -netdev type=vhost-user,id=netdev1,chardev=char0,vhostforce \
   -device virtio-net-pci,netdev=netdev1,mac=52:54:00:00:00:01,disable-modern=true,mrg_rxbuf=on \
   -vnc :10
   

4. On VM, bind virtio net to vfio-pci and run testpmd

   ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0x3 -n 3 -- -i \
   --nb-cores=1 --txd=1024 --rxd=1024
   testpmd>set fwd mac
   testpmd>start
   

5. Send packet by packet generator with different packet sizes(68,128,256,512,1024,1280,1518),repeat below command to get throughput 10 times,then calculate the average throughput:

   testpmd>show port stats all
   

243.4. Test Case 2: PVP test with virtio 1.0 mergeable path

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

   rm -rf vhost-net*
   ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xe -n 4 \
   --vdev 'eth_vhost0,iface=vhost-net,queues=1' -- \
   -i --nb-cores=1 --txd=1024 --rxd=1024
   testpmd>set fwd mac
   testpmd>start
   

2. Check dut machine already has installed different version qemu, includes [qemu-5.2.0, qemu-6.2.0, qemu-7.0.0, qemu-7.1.0, qemu-7.2.0].

3. Go to the absolute_path of different version qemu,then launch VM with different version qemu, note: we need add “disable-modern=false” to enable virtio 1.0:

   qemu-system-x86_64 -name vm2 -enable-kvm -cpu host -smp 2 -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 \
   -netdev user,id=netdev0,hostfwd=tcp:127.0.0.1:6002-:22 \
   -chardev socket,id=char0,path=./vhost-net \
   -netdev type=vhost-user,id=netdev1,chardev=char0,vhostforce \
   -device virtio-net-pci,netdev=netdev1,mac=52:54:00:00:00:01,disable-modern=false,mrg_rxbuf=on \
   -vnc :10
   

4. On VM, bind virtio net to vfio-pci and run testpmd:

   ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0x3 -n 3 -- -i \
   --nb-cores=1 --txd=1024 --rxd=1024
   testpmd>set fwd mac
   testpmd>start
   

5. Send packet by packet generator with different packet sizes(68,128,256,512,1024,1280,1518),repeat below command to get throughput 10 times,then calculate the average throughput:

   testpmd>show port stats all
   

243.5. Test Case 3: PVP test with virtio 1.1 mergeable path

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

   rm -rf vhost-net*
   ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xe -n 4 \

3. Go to the absolute_path of different version qemu,then launch VM with different version qemu, note: we need add “disable-modern=false,packed=on” to enable virtio 1.1:

   qemu-system-x86_64 -name vm2 -enable-kvm -cpu host -smp 2 -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 \
