proxmox PCI passthrough with windows, Geforce 1070, Ryzen, and B450 Tomahawk
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:
I needed to enable 3 main things:
- WHQL for windows 10
- UEFI Bios
- enable virtualization under the Overclocking-> CPU Features panel
/etc/default/grub needs to have the following DEFAULT line:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet amd_iommu=on iommu=pt video=efifb:off”
/etc/modprobe.d/blacklist.conf needs the following entry:
QEMU Host config

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