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

[Burakov, Anatoly]

Hi Sujith

Not that I know of, no. There are other ways to run physical NICs in a VM though, you don't require VFIO for that.

Thanks,
Anatoly

Hi Anatoly,

Has anything happened in this front?  Do you see running of DPDK in guest OS on KVM with physical NIC passed through to it happening soon?

Thanks,
