Loaded the Igb_Uio module 2. Loaded the KNI module 3. Allocated HugePages 4.Ran the PktGen with the following command ./app/build/pktgen -c 0x1 -n 3 --proc-type auto --file-prefix pg -- -P Can you please help me in solving the issue. PS: I thought the error is due to insufficient number of huge pages, so I increased the number of hugepages and tried. Still facing the same issue. DPDK version 1.7 PktGen 2.5.6 -- Thanks & Regards, Venkateswara Rao Dokku.
