When I tried to launch test-pmd on KVM guest of Fedora21, I got following error:
Configuring Port 0 (socket 0) Fail to configure port 0 tx queues EAL: Error - exiting with code: 1 Cause: Start ports failed I found that the error caused here, and actual error message was "TX checksum offload not supported": http://dpdk.org/browse/dpdk/tree/lib/librte_pmd_virtio/virtio_rxtx.c#n425 This patch adds default_txconf on virtio pmd, to avoid the error.
