 Hi Keith,

Sorry for replying after after long days as I was involved in different module so not able to to track down this issue. Now once again back to this module.  This time I had executed pktgen-DPDK in Host machine and Bridge and DPDK ports configuration done in guest machine (VM). Please find attachment for bridge and dpdk-ports creation in guest machine. 

Facing same issue "ports not found" and as well as this below issue:

Pktgen-dpdk uses the first core in the CPU list for display and timers, so
you need to make sure you a lot one extra core for that function.

./app/build/pktgen -c 0x07 -n 2 ‹proc-type auto ‹ -m ü1.0, 2.1ý

Note also the ports start at zero to N, notice in the above I skipped core
zero and used 1 and 2 instead.

As for the error above DPDK did not find any ports that were usable and
this normally means the ports have not been attached to the igb_uio device.

Please do the following and show the output:

# lspci | grep Ethernet

# dpdk_nic_bind.py ‹status

Also the Pktgen-dpdk has a readme or you can look at the DPDK docs as well
for more information.

Thanks
++Keith
