My scenario: I wanted to use Hyper-V's GPU Partitioning and WSL technology inside a Proxmox Virtual machine so that I could continue using Linux natively while taking advantage of Microsoft's groundbreaking virtualization features.

Problem

There is a vulnerability with the Ryzen Processor that allows a nested virtual machine's application to crash the underlying host system and even compromise the host entirely.

Windows VM

Using GPU-PV, you can create a partition of your GPU and assign it to a Windows virtual machine

• Use this interactive tool to automate the process of installing and setting up a GPU-PV virtual machine
• Connect to the virtual machine

Make sure your GPU is visible.
