Thanks Marcel!!!
After tailing the logs and basic troubleshooting, we finally can have 2 VMs
to ping to each other. One dpdkvhostuser interface is for each VM and we
have to new add flows based on dpdkvhostuser ofport numbers.
Another issue we might post it to proper mail loop is that we run
pktgen-dpdk 2.9.1 inside of VM but no packets counted from pktgen terminal
display. It is so weird that we only see 128 tx packets bursted out and
then nothing is continue working. After that, we try to dump-flows via
ovs-ofctl utility but it shows "connection refued". I am not sure have any
one of you guys ideas here? Thanks!!!
