[dpdk-dev] DPDK bond the virtio NIC run error

[Hu, FangyinX]

HI, I use the qemu-kvm create a virtual machine and give a virtio-net-pci mode NIC to the VM, then I run the bond_app example get an error. Here is the steps.

1.       qemu-kvm -enable-kvm -had /home/images/fedora.qcow2 -m 2048 -smp 8 -cpu qemu64,+ssse3,+sse4.2 -device virtio-net-pci,netdev=mytap -netdev tap,id=mytap,ifname=tap1,script=/etc/qemu-ifup,downscript=no -device pci-assign,host=03:00.1

2.       compile the DPDK v2.1.0-rc3 and use the tools/dpdk_nic_bind.py script to bind the device to the igb_uio

3.       execute the example/bond/build/bond_app -c f -n 2  and get the error:

EAL: memzone_reserve_aligned_thread_unsafe(): memzone <port0_rvq0> already exists

PMD: slave_configure(1351) - rte_eth_tx_queue_setup: port=0 queue_id 0, err (-22)

PMD: bond_ethdev_start(1497) - bonded port (2) failed to reconfigure slave device (0)

EAL: Error - exiting with code: -1

Cause: Start port 2 failed (res= -1)

Are the rx_mode.hw_vlan_*  enabled on default? 
You may disable it first and try it again.
