+vm2vm vhost-user/virtio-net test plan
+=====================================
+
+Description
+===========
+
+This test plan test several features in VM2VM topo:
+1. Check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and
+packed ring vhost-user/virtio-net mergeable path with CBDMA channel.
+2. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring when
+vhost enqueue operation with multi-CBDMA channels.
+Note:
+1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1.
+2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version > LTS 4.2.1,
+DUT to old qemu exist reconnect issue when multi-queues test.
+3.For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.
+
+
+For more about dpdk-testpmd sample, please refer to the DPDK docments:
+https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html
+
+For virtio-user vdev parameter, you can refer to the DPDK docments:

+
+Prerequisites
+=============
+
+Topology
+--------
+      Test flow: Virtio-net-->Vhost-->Testpmd-->Vhost-->Virtio-net
+
+Hardware
+--------
+      Supportted NICs: ALL
+
+Software
+--------
+      Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz
+
+General set up
+--------------
+1. Compile DPDK::
+
+      # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=<dpdk build dir>
+      # ninja -C <dpdk build dir> -j 110
+
+2. Get the PCI device ID and DMA device ID of DUT, for example, 0000:18:00.0 is PCI device ID, 0000:00:04.0, 0000:00:04.1 is DMA device ID::
+
+      <dpdk dir># ./usertools/dpdk-devbind.py -s
+
+      Network devices using kernel driver
+      ===================================
+      0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci

+Test case
+=========
+
+Common steps
+------------
+1. Bind 2 CBDMA channels to vfio-pci::
+
+      <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port DMA device id>
+
+      For example, Bind 1 NIC port and 2 CBDMA channels::
+      <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:00:04.0,0000:00:04.1
+
+Test Case 1: VM2VM split ring vhost-user/virtio-net CBDMA enable test with tcp traffic

+
+1. Bind 2 CBDMA channels to vfio-pci, as common step 1.
+
+2. Launch vhost by below command::

+3. Launch VM1 and VM2 with qemu::
+
+	taskset -c 32 qemu-system-x86_64 -name vm1 -enable-kvm -cpu host -smp 8 -m 4096 \
+	-object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on \

+
+4. On VM1, set virtio device IP and run arp protocal::
+
+	ethtool -L ens5 combined 8
+	ifconfig ens5 1.1.1.2
+	arp -s 1.1.1.8 52:54:00:00:00:02
+
+5. On VM2, set virtio device IP and run arp protocal::
+
+	ethtool -L ens5 combined 8
+	ifconfig ens5 1.1.1.8
+	arp -s 1.1.1.2 52:54:00:00:00:01
+
+6. Scp 1MB file form VM1 to VM2::
+
+	Under VM1, run: `scp [xxx] root@1.1.1.8:/`   [xxx] is the file name
+
+7. Check the iperf performance between two VMs by below commands::
+
+	Under VM1, run: `iperf -s -i 1`
+	Under VM2, run: `iperf -c 1.1.1.2 -i 1 -t 60`
+
+8. Rerun step 5-6 five times.
