igb_uio fails on VirtualBox virtio

Hi,

I am getting a "write error: No such device" when:
echo  0000:00:08.0 > /sys/bus/pci/drivers/igb_uio/bind

This is on Virtualbox with a virtio based adapter.

This also fails when using the dpdk pci_unbind:
./tools/pci_unbind.py —bind=igb_uio 00:08.0
Cannot bind to driver igb_uio

I have read (http://dpdk.org/doc) that the dpdk (I am using version 1.6) supports virtio on virtual box. Is it truly supported?
If yes, any clue on what is the problem?

Thanks,

Reda
