Hello! I'm trying to do a PCI passthrough of my GPU to Windows 10 guest
machine using libvirt and vfio-pci. I've followed Alex Williamson's
guide from vfio-blog
http://vfio.blogspot.com/2015/05/vfio-gpu-how-to-series-part-3-host.html
and it still doesn't work as i'm getting Code 43 on my MSI nVidia GTX
660 graphics card. Dumping all necessary info below (if you need me to
supply more, i'll be happy to do it):
