Has anybody successfully linux-gamed on proxmox VE? (lemmy.ml)

I'm extensively looking to setting up gaming on linux inside a VM on proxmox VE. But nothing i've tried worked.

I'm trying out bunch of games through Steam and its proton compatibility layer. Games I tried:

Sekiro
Elden Ring
Dark Souls 3

I've tried:

Manjaro KDE
Bazzite

on VM:

I was successfully install Windows 10 inside a VM and run games on there. By following this reddit post

But on any linux VM attempts, games can go 'starting' but back to 'launch' in a few seconds. It just fails...

I just want to know if anybody has ever successfully done this:D

that reddit post is from 6 years ago so its probably a bit out of date. Follow the pve wiki

You need to use uefi instead of seabios per your screenshot

Are you passing through a GPU? If so, are you sure the proxmox host isn't using it?

Edit: Just saw the link in the post was to a GPU passthrough guide, so better question, do you see the GPU from within the VM?

I've admittedly never tried gaming on a linux VM or LXC in proxmox, but I've done other tasks that required GPU hardware acceleration with no issues with both.

I've passed through my GPU for acceleration purposes which has worked pretty well. I don't see a passed-through GPU in your screenshot. I'll assume you turned on the correct IOMMU and SR-IOV settings, added the PCI:E hardware to that VM, and made sure it showed up inside the guest OS?

Yup! The screenshot can be confiding because I tinker a lot with cpu, memory, pcie etc. I made it work with gpu pass through etc. so it was hard for me to capture exact setup in a single screenshot. in fact, games that don’t require proton runs very well like Celeste.

how did you pass through the gpu if it's not visible on that list?

[-] Telorand@reddthat.com 2 points 1 month ago

Don't know much about proxmox, but I know that Hyper-V tries to create every VM with Secure Boot turned on, and every Linux distro I've tried won't boot the installer like that.

Maybe double check the settings of the VM.
