I am using Virtual Box Version 4.2.18 r88780, dpdk-1.5.1r1 and Fedora
19 with 3.11.9 kernel. I have one e1000 and one virtio-net NIC eth2
and eth3 respectively. eth2 is used for ssh access to the VM. I am
trying to get testpmd working on eth3 using the librte_pmd_virtio.so
driver. I have changed the defconfig_i686-default-linuxapp-gcc file to
disable the native virtio driver. I am getting the "virtio-net device
is already used by another driver" message. Any idea what could be
wrong? Any help is appreciated.
Thanks,
Srini
