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,
idle_age=0, in_port=3 actions=output:4
