[dpdk-dev] [PATCH 00/16] [RFC] [VFIO] Add VFIO support to DPDK

[Burakov, Anatoly]

Hi Sujith

Of course you can. Just use the igb_uio driver instead. Refer to the Getting Started Guide from Intel, it'll walk you through the steps, although they are basically the same as for VFIO.

Thanks,
Anatoly

Anatoly,
Thanks for the quick response !

I am able do PCI passthrough and use the NIC in the guest OS.
What I¹m trying to do is run DPDK in the guest and make use of the passed-through NIC.  Without using VFIO, could I achieve this?

Thanks,
-Sujith
