Hi Billy,

This patch is useful only if you want to pass through the graphic card
as a primary on the guest.

We've got good result when we pass through a legacy nvidia graphic
card as secondary in the guest (just put pci = ['B:D:F']) in your config
file. You need to install at least the version 178.12 for of the nvidia
driver.
