No more need to hide the hypervisor
Ever since I started to run a Microsoft Windows VM with GPU passthrough, Nvidia graphics drivers would only support their professional Quadro line of graphics cards in a virtual machine. Ten years ago I bit the bullet and bought an outrageously expensive Nvidia Quadro 2000 GPU. Truth be told – it’s been and still is a great GPU and I currently use it for my Linux host. Back then the Quadro was passed through to a Windows 7 VM running on Xen. It worked great. Continue reading “Nvidia And The “hidden state””

A question that frequently pops up in VFIO or GPU passthrough forums is which graphics card to buy: AMD or Nvidia? And the answer often depends on whom you ask.
Some people will tell you to stay clear of Nvidia graphics cards since their driver detects the virtual machine and quits.
Others mention the “reset bug” that’s been haunting AMD graphics cards for the last couple of years (see Wendells video interview of Linux kernel maintainer Greg Kroah-Hartman). So what’s the story? Continue reading “Graphics Cards: AMD vs Nvidia”
For some time I wanted to run a kvm virtual machine with GPU passthrough on a low-end Asus H110M-K D3 motherboard with an i3-6100 CPU and an Nvidia GTX 1060 GPU, but never found the time. Now I finally had a chance to give it a try. While the preparations were easy, I ran into a problem when starting the Windows 10 VM:
