+3. On VM1, set virtio device IP, send 10M packets from packet generator to nic then check virtio device can receive packets::

+    tcpdump -i [ens3]
+

+    ./dpdk-devbind.py -u [00:03.0]   # [00:03.0] is the pci addr of virtio-net
+    ./dpdk-devbind.py -b virtio-pci [00:03.0]
+
+5. Check virtio device can receive packets again::
+
+    ifconfig [ens3] 1.1.1.2
+    tcpdump -i [ens3]
+
+6. Rerun step4 and step5 100 times to check event idx workable after driver reload.

+    rm -rf vhost-net*

+    taskset -c 32-33 \
+    qemu-system-x86_64 -name us-vhost-vm1 \
+     -cpu host -enable-kvm -m 2048 -object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on -numa node,memdev=mem -mem-prealloc \

+     -vnc :12 -daemonize
+
+3. On VM1, give virtio device ip addr and enable vitio-net with 16 quques::
+
+    ifconfig [ens3] 1.1.1.2           # [ens3] is the name of virtio-net
+    ethtool -L [ens3] combined 16
+
+4. Send 10M different ip addr packets from packet generator to nic, check virtio-net interrupt times by below cmd in VM::
+
+    cat /proc/interrupts
+
+5. After two hours stress test, stop and restart testpmd, check each queue has new packets coming::
+
+    testpmd>stop
+    testpmd>start
+    testpmd>stop
