I tried doing this years ago, and never quite go it to work. Some of the software involved in that article simply didn't exist yet, and GPUs weren't shipping with SR-IOV support yet (instead, I did Intel iGPU for Linux fbcon, real AMD GPU fed directly to the Windows VM with PCI-E Passthrough). In the end, I bailed on that dream and moved the Linux install to its own smaller machine, and ran Windows bare on the big machine. The problem was, if the GPU locked up hard, and GPUs back then would not respond to PCI Device Reset, if it wasn't something that merely re-initializing it on VM restart would fix... I had to restart the entire machine, thus defeating the purpose of having Windows in the VM in the first place! All my long-lived processes now run on the stand-alone Linux machine, and anything that is free to explode runs on my Windows machine. Windows gets wonky? Restart, ssh back into my screen sessions, reopen the browser, restart a bunch of cloud slaved apps, tada.

I got into writing this actually because graphics sharing was such a bad experience that I would usually run a Windows host and then Linux guests in something like VirtualBox or VMWare Workstation. I always wanted a host with fault tolerant guests but GPU sharing features seemed to be locked to "enterprise GPUs" and it wouldn't work on my consumer GPU. This solves some of those problems I was having and lets me run Linux on my host with a full performance Windows guest (at least for me it does).

  As the Nvidia Linux driver doesn't support DSC (Display Stream Compression), a lot of people are having problems driving 4k/240hz and 8k/60hz displays with DP 1.4 and HDMI 2.1. Frustratingly this works fine using Windows. Any ideas on how to run Linux guests on a Windows host while sharing the GPU like libvf.io? This would allow us work around the DSC issue until Nvidia implements support.
