+Packed ring pvp reconnect test plan
+===================================
+
+Description
+===========
+
+Vhost-user uses Unix domain sockets for passing messages. This means the DPDK vhost-user implementation has two options:
+
+* DPDK vhost-user acts as the server:
+  DPDK will create a Unix domain socket server file and listen for connections from the frontend.
+  Note, this is the default mode, and the only mode before DPDK v16.07.
+
+* DPDK vhost-user acts as the client:
+  Unlike the server mode, this mode doesn't create the socket file;it just tries to connect to the server (which responses to create the file instead).
+  When the DPDK vhost-user application restarts, DPDK vhost-user will try to connect to the server again. This is how the "reconnect" feature works.
+  When DPDK vhost-user restarts from an normal or abnormal exit (such as a crash), the client mode allows DPDK to establish the connection again. Note
+  that QEMU version v4.2.0 or above is required for this reconnect feature.
+  Also, when DPDK vhost-user acts as the client, it will keep trying to reconnect to the server (QEMU) until it succeeds. This is useful in two cases:
+    * When QEMU is not started yet.
+    * When QEMU restarts (for example due to a guest OS reboot).
+
+Test Case1: vhost-user/virtio-pmd pvp reconnect from vhost-user
+===============================================================
+Flow: TG--> NIC --> Vhost --> Virtio --> Vhost--> NIC--> TG
+
+1. Bind one port to igb_uio, then launch vhost with client mode by below commands::
+
+    ./testpmd -c 0x30 -n 4 --socket-mem 1024,1024 --legacy-mem --vdev 'eth_vhost0,iface=vhost-net,client=1,queues=1' -- -i --nb-cores=1
+    testpmd>set fwd mac
+    testpmd>start
+
+2. Start VM with 1 virtio device, and set the qemu as server mode::
+
+    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 \

+    -vnc :10
+
+3. On VM, bind virtio net to igb_uio and run testpmd::
+
+    ./testpmd -c 0x3 -n 4 -- -i --nb-cores=1 --txd=1024 --rxd=1024
+    testpmd>set fwd mac
+    testpmd>start
+
+4. Send packets by packet generator, check if packets can be RX/TX with virtio-pmd::
+
+    testpmd>show port stats all
+
+5. On host, quit vhost-user, then re-launch the vhost-user with below command::
+
+    testpmd>quit
+    ./testpmd -c 0x30 -n 4 --socket-mem 1024,1024 --legacy-mem --vdev 'eth_vhost0,iface=vhost-net,client=1,queues=1' -- -i --nb-cores=1
+    testpmd>set fwd mac
+    testpmd>start
+
+6. Check if the reconnection can work, still send packets by packet generator, check if packets can be RX/TX with virtio-pmd::
+
+    testpmd>show port stats all
+

+3. Launch VM1 and VM2::
+
+    qemu-system-x86_64 -name vm1 -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,vlan=2,macaddr=00:00:00:08:e8:aa,addr=1f \
+    -net user,vlan=2,hostfwd=tcp:127.0.0.1:6002-:22 \
+    -chardev socket,id=char0,path=./vhost-net,server \
+    -netdev type=vhost-user,id=netdev0,chardev=char0,vhostforce \
+    -device virtio-net-pci,netdev=netdev0,mac=52:54:00:00:00:01,mrg_rxbuf=on,rx_queue_size=1024,tx_queue_size=1024,packed=on \
+    -vnc :10
+
+    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/ubuntu16-1.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,vlan=2,macaddr=00:00:00:08:e8:aa,addr=1f \
+    -net user,vlan=2,hostfwd=tcp:127.0.0.1:6003-:22 \
+    -chardev socket,id=char0,path=./vhost-net1,server \
+    -netdev type=vhost-user,id=netdev0,chardev=char0,vhostforce \
+    -device virtio-net-pci,netdev=netdev0,mac=52:54:00:00:00:02,mrg_rxbuf=on,rx_queue_size=1024,tx_queue_size=1024,packed=on \
+    -vnc :11
+
+4. Set virtio device IP and run arp protocal on two VMs::
+
+    VM1: ifconfig ens4 1.1.1.2
+    VM2: ifconfig ens4 1.1.1.3
+    VM1: arp -s 1.1.1.3 52:54:00:00:00:02
+    VM2: arp -s 1.1.1.2 52:54:00:00:00:01
+
+5. Run iperf on VM1 and VM2, check the tso enabled performance for 1 min::
+
+    VM1: iperf -s -i 1 -t 60
+    VM2: iperf -c 1.1.1.2 -t 60 -i 1
+
+6. Reboot VM1 and VM2, rerun step3-step5, ensure the vhost-user can reconnect to VM again, and the iperf traffic can be continue.
+
+Test Case 9: vhost-user/virtio-net VM2VM reconnect stability test
+=================================================================
+Flow: Virtio-net1 --> Vhost-user --> Virtio-net2
+
+Similar as Test Case 7, all steps are similar except step 6.
+
+6. Quit vhost-user, then re-launch, repeat it 5-8 times, check if the reconnect can work and ensure the traffic can continue.
+
+7. Reboot two VMs, then re-launch VMs, repeat it 3-5 times, check if the reconnect can work and ensure the traffic can continue.
