Anatoly,
Thanks for the quick response !
I am able do PCI passthrough and use the NIC in the guest OS.

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,

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,

My 2 cents:
Hi Chris,

That's correct, virtio will not work with VFIO as it stands. However it's not
the fault of this patch but rather lack of emulated IOMMU on the guest :-)

Hi Stephen,

VFIO is Linux-only, and in theory will be able to work on the guest, but not at
the moment, since it requires IOMMU. There was a GSoC proposal for KVM to do
IOMMU implementation, and there were a few AMD IOMMU-emulation patches
This patchset adds support for using VFIO instead of IGB_UIO to
map the device BARs.
VFIO is a kernel 3.6+ driver allowing secure DMA from userspace
by means of using IOMMU instead of working directly with physical
memory like igb_uio does.
Short summary:
* Adding support for VFIO in EAL PCI
