I set up my first Proxmox implementation on my rebuilt gaming PC.  The goal was to run proxmox on bare metal, then run a windows VM with hardware passthrough so I could play Elite Dangerous in windows with only a 1-3% performance loss. This would also give me a platform to work on automation tools and containerization.

So how did I go about doing it? Well, I started by reading this article: https://techblog.jeppson.org/2018/03/windows-vm-gtx-1070-gpu-passthrough-proxmox-5/

That did most of the heavy lifting, but it was specific to intel processors. Here’s what my final changes looked like:

BIOS

I needed to enable 3 main things:

• WHQL for windows 10
• UEFI Bios
• enable virtualization under the Overclocking-> CPU Features panel

GRUB

/etc/default/grub needs to have the following DEFAULT line:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet amd_iommu=on iommu=pt video=efifb:off”

Modprobe blacklist

/etc/modprobe.d/blacklist.conf needs the following entry:

blacklist radeon
blacklist nouveau
blacklist nvidia
blacklist amdgpu

I apologize that this is super rough and poorly formatted, but I figured that was better than nothing.
