+6. Check vhost related cores are waked up with l3fwd-power log, such as following::
+
+ L3FWD_POWER: lcore 0 is waked up from rx interrupt on port 0 queue 0
+ ...
+ ...
+ L3FWD_POWER: lcore 15 is waked up from rx interrupt on port 0 queue 15
+
+Test Case 8: wake up split ring vhost-user cores by multi virtio-net in VMs with event idx interrupt mode and cbdma enabled test
+================================================================================================================================
+
+1. Bind two cbdma ports to igb_uio driver, then launch l3fwd-power example app with client mode::
+
+ ./l3fwd-power -l 1-2 -n 4 --log-level=9 \
+ --vdev 'eth_vhost0,iface=/vhost-net0,queues=1,client=1,dmas=[txq0@00:04.0]' \
+ --vdev 'eth_vhost1,iface=/vhost-net1,queues=1,client=1,dmas=[txq0@80:04.0]' \
+ -- -p 0x3 --parse-ptype 1 --config "(0,0,1),(1,0,2)"
+
+2. Launch VM1 and VM2 with server mode::
+
+ taskset -c 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 \
+ -smp cores=1,sockets=1 -drive file=/home/osimg/ubuntu1910.img \
+ -monitor unix:/tmp/vm2_monitor.sock,server,nowait -device e1000,netdev=nttsip1 \
+ -netdev user,id=nttsip1,hostfwd=tcp:127.0.0.1:6003-:22 \
+ -chardev socket,server,id=char0,path=/vhost-net0 \
+ -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
+ -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,csum=on -vnc :10 -daemonize
+
+ taskset -c 34 \
+ qemu-system-x86_64 -name us-vhost-vm2 \
+ -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 \
+ -smp cores=1,sockets=1 -drive file=/home/osimg/ubuntu1910-2.img \
+ -monitor unix:/tmp/vm2_monitor.sock,server,nowait -device e1000,netdev=nttsip1 \
+ -netdev user,id=nttsip1,hostfwd=tcp:127.0.0.1:6004-:22 \
+ -chardev socket,server,id=char0,path=/vhost-net1 \
+ -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
+ -device virtio-net-pci,mac=52:54:00:00:00:02,netdev=mynet1,csum=on -vnc :11 -daemonize
+
+3. Relauch l3fwd-power sample for port up::
+
+ ./l3fwd-power -l 1-2 -n 4 --log-level=9 \
+ --vdev 'eth_vhost0,iface=/vhost-net0,queues=1,client=1,dmas=[txq0@00:04.0]' \
+ --vdev 'eth_vhost1,iface=/vhost-net1,queues=1,client=1,dmas=[txq0@80:04.0]' \
+ -- -p 0x3 --parse-ptype 1 --config "(0,0,1),(1,0,2)"
+
+4. On VM1, set ip for virtio device and send packets to vhost::
+
+ ifconfig [ens3] 1.1.1.2
+ #[ens3] is the virtual device name
+ ping 1.1.1.3
+ #send packets to vhost
+
+5. On VM2, also set ip for virtio device and send packets to vhost::
+
+ ifconfig [ens3] 1.1.1.4
+ #[ens3] is the virtual device name
+ ping 1.1.1.5
+ #send packets to vhost
+
+6. Check vhost related cores are waked up with l3fwd-power log.
