Five VM with dpdkvhostuser port, in one physical server(openstack compute
node), connect to ovs bridge br-int.
some info of compute node :
[root@node-10 ~]# ps -ef | grep ovs
root 10468 1 99 10:59 ? 1-08:07:33 ovs-vswitchd --dpdk -c 0x4

--log-file=/var/log/openvswitch/ovs-vswitchd.log
--pidfile=/var/run/openvswitch/ovs-vswitchd.pid --detach
[root@node-10 ~]# ovs-vsctl show

br-int connect to the br-vlan by patch port, and br-vlan has a dpdk type port
connect to another physical server(openstack network node).
all five VM has the same image,and same cpu/memory.... , every VM works as
netperf server.
now ,in the network node , spawn netperf client, send tcp flow to all five VM.
[root@node-4 ~]# for i in `seq 43 47`; do ip netns exec
qrouter-0cea5044-82f1-4ee7-a290-17c528aacc9c netperf -t TCP_RR -H 100.64.8.$i
-l 10 & done
