[vfio-users] Problem with installing Windows drivers for Quadro M2000M(GM107GLM)

[Jack Coulter]

Given that Intel's GVT patches may potentially be merged in 4.10, I'm
curious as to whether this will change the VFIO + Optimus situation.

Since GVT works with unmodified guest drivers for the Intel card, and
can provide either direct access to the IGPU's outputs or work in a
composited mode, is it possible that a Optimus cards might finally be
usable in VMs if the IGPU is made available to the VM via GVT? If not,
what further work would be required for such a setup to work with VFIO?
