igb_uio fails on VirtualBox virtio

igb_uio fails on VirtualBox virtio

[Reda Haddad]

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

You should use another virtio because it avoids uio constraints.

I have been using it to run testpmd on Virtualbox longtime ago.

See http://dpdk.org/browse/virtio-net-pmd/

Thanks for the info.

I guess the referenced virtio-net-PMD below is dpdk1.3 compatible but not necessarily a newer version. So I assume will need to update it for 1.6, etc.

So, can anyone confirm that the intel-provided virtio pmd with dpdk 1.6 does NOT work with virtual box?

Where do you see that it does not support the latest on dpdk.org?
   http://dpdk.org/browse/virtio-net-pmd/log/virtio_user.c

About 1.6, stay tuned.

you have the source code...

I tried to compile it on 1.6 and it failed.

It failed for me. So I wanted to check if someone managed to compile it.
