[dpdk-dev] [ dpdk-pktgen execution issue ] Error: Didn't find any ports to use

[Arkajit Ghosh]

Hi,

Facing issue during the execution of dpdk-pktgen in VM. 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 at tcs-VirtualBox:/usr/src/pktgen-DPDK/dpdk/examples/pktgen# /usr/src/ovs/utilities/ovs-vsctl show
c2245b31-3ca1-49c6-b4c5-1041be5b9dc4
    Bridge "ovsbr0"
        Port "dpdkr2"
            Interface "dpdkr2"
                type: dpdk
                options: {port="2"}
        Port "ovsbr0"
            Interface "ovsbr0"
                type: internal
        Port "dpdkr1"
            Interface "dpdkr1"
                type: dpdk
                options: {port="1"}
root at tcs-VirtualBox:/usr/src/pktgen-DPDK/dpdk/examples/pktgen# 

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
