Hi, I am just trying out DPDK in a fedora 18 KVM guest and have an issue when I am trying l2fwd application.
I am binding eth1, eth2 interfaces using below commands ./igb_uio_bind.py --bind=igb_uio eth1 ./igb_uio_bind.py --bind=igb_uio eth2 When I run l2fwd app I get following error ./l2fwd -c 1 -n 4 EAL: Cannot read numa node link for lcore 0 - using physical package id instead EAL: Detected lcore 0 as core 0 on socket 0 EAL: Setting up memory...
