Hi DPDK-USERS,
1. I have installed DPDK on my virtual-box which runs ubuntu 16.04.1
(xenial).
2. My DPDK version is 16.07
3. When i try to bind ethernet device to VFIO module i get the following
error
Error: bind failed for 0000:00:08.0 - cannot bind to driver vfio-pci [
this is for NIC 82545EM]
debug message gave the rrror
vfio-pci: probe of 0000:00:08.0 failed with error -22
Please Advice.
Thanks
Raman

Hey Raman,
Check dmesg for the details. I guess you have no IOMMU enabled, so you
should either go ahead and enable it wit intel_iommu=on or use
uio_pci_generic or igb_uio module instead of vfio-pci.
Regards,
Andriy

Hi,
FYI vfio-pci is not supported inside a VM yet:
https://lists.gnu.org/archive/html/qemu-devel/2015-11/msg04284.html
It is a work in progress (slide 19):

Sergio

Hi Sergio/Alex,
Thanks for your reply. I will use uio_pci_generic and take it forward.
Thanks
Raman
