Hi,
Facing issue during the execution of dpdk-pktgen. Please find the below details:
Setup details:
> Executing in Guest machine (VM).
> Having 2 logical core.
>Configured 2048 km hugepages
>Number of processor: 2
Scenario to verify: Generate some packets by dpdk-pktgen and then one
dpdk-ports will work as a RX end and other one will be as TX end to handle the
incoming packets and do the required action.
dpdk-Ports creation: Here is the snapshot
root@tcs-VirtualBox:/usr/src/pktgen-DPDK/dpdk/examples/pktgen#
/usr/src/ovs/utilities/ovs-vsctl show

Added the Flow Entrys:
# Add flows between port 1 (dpdk0) to port 2 (dpdk1)
./ovs-ofctl add-flow ovsbr0 in_port=1,action=output:2
./ovs-ofctl add-flow ovsbr0 in_port=2,action=output:1
