Hi lifuqiong,
Could you provide the output of the following commands in your setup?:
ovs-vsctl show
ovs-ofctl dump-flows
ovs-ofctl dump-ports

Hi Mauricio:
I changed my qemu version from 2.2.1 to 2.5.0 and the vms can
communication with each other. But the VM cannot ping PC in the outside
network. They in a same subnet.
PC(192.168.0.103/24) ping vm(192.168.0.90); vm’s host’s dpdk NIC and PC are in
a L2 switch. And DPDK NIC connected to switch’s Port Eth1/0/8
Investigation:
Binding VM’s IP and Mac in PC’s ARP table, and binding VM’s Mac in
Port Eth1/0/8; PC is pinging vm, I can see Output packets of Eth1/0/8
increasing regularly, which means the ping request packet has send to DPDK NIC.
But the VM can not receive the packet?
My switch has NO vlan , the default VLAN is 1. But when I ping from
vm1 to vm2 , showing MaC address in OVS which shows as follows:
port VLAN MAC Age
4 0 00:00:00:00:02:12 1
3 0 00:00:00:00:00:04 1
What was the reason why VM cannot communication with the PC? Thank you

Hello lifuqiong,
I faced the same problem some days ago
(http://openvswitch.org/pipermail/dev/2016-March/068282.html), the bug is
already fixed.
Where are you downloading OVS from?, it appears that the bug is still present
in the version on http://openvswitch.org/releases/openvswitch-2.5.0.tar.gz,
please download ovs from git and switch to branch-2.5.
Mauricio Vasquez,

I want to test dpdk vhost-user port on ovs to follow
https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ovs-today-using-dpdk-200;
I create ovs+dpdk environment followed INSTALL.DPDK.md; and create 2 VM2, try
to ping each other but show me “Destination Host Unreachable”;
Dump-flows shows packets matched the flow, but can’t output to port 4, why ? I
can’t get any useful error or warning info from ovs-vswitchd.log.
While ping from vm1 to vm2, statistics on vm1 shows that eth1 RX_packet keeps
zero, TX_PACKET keeps increasing.
