主题: ovs + dpdk vhost-user match flows but cannot execute actions

 

         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-ov
s-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.

 

ovs-ofctl dump-flows ovsbr0

NXST_FLOW reply (xid=0x4):

cookie=0x0, duration=836.946s, table=0, n_packets=628, n_bytes=26376,
