I’ve always found the documentation around virtio-GPU and virtgl very lacking, and have never gotten them working. Would love to get pointers if anyone has a good source.

I don’t see any performance differences with the vgpu actually. I have more performance bottlenecks with the CPU, and my RAM isn’t the fastest, so I think I’m more CPU limited. Benchmarks I have run that are GPU focused seem to show little to no difference from what the physical card would do.
Yeah unfortunately. 20xx is last generation supported so far via the patch, not sure if support for later cards is coming or not.
No, but I think you’d have some problems. Only the host has access to the actual DisplayPort outputs, all the vgpus have virtual displays, I don’t think there’s a way to make them use the physical out.
Sure, but you’ll get diminishing returns most likely as consumer hardware doesn’t really have the resources to scale that way very well if all the VMs are running demanding apps simultaneously.
Even for something like 4 VMs that just do NVenc, there are limits for how many streams the GPU can do. I think there’s another patch that lets you raise that, but at some point you’ll run out of resources quick. Even powerful consumer gear isn’t really designed to be used by more than one user/app and it starts to show the more you virtualize and split those resources.
I’ve been doing exactly that at home for a couple years now. First with Parsec, now Sunshine/Moonlight.
Host is Proxmox on Ryzen 5800x, 64gm RAM GPU is 2070 Super, with VGPU patched drivers from https://gitlab.com/polloloco/vgpu-proxmox
When I’m gaming I’ll dedicate the full 8Gb to my windows Vm, otherwise I split it in 2 or 4Gb chunks to Jellyfin or my home camera monitoring. 8gb can’t split very many ways, and most things require at least 2 to run.
Locally at home I can run 1440p 60fps rock solid over wifi on any device, from my phone/old laptop/apple tv/raspberry pi. Remote I can do 1080p60, but a bit more hit or miss depending on my network connection.
Experimenting with LLMs I’ve done through the same windows VM, or to a ubuntu dev VM. Works the same way. I’m thinking of transitioning my gaming VM to Linux too.
The amount of VRAM is the hard limitation to get past, the virtualization tech itself has been there for a while.
But to be perfectly honest……it really was just a “let’s see if I could do this” type task, direct GPU pass though is more straightforward and it’s not really worth splitting 8Gb these days. Unless you get a card with significantly more VRAM passthrough is much less work.
I suspect we got off on the wrong foot when I called it a product instead of just a project idea, but I don’t actually disagree with that stance. Cheers.
That’s the act I was thinking of. I’m almost certain web streamers will say it doesn’t apply to them……and it’s definitely one of those things you’d take for granted until you hit the “new” streaming medium and realize why it was necessary in the first place.
And you came here with nothing productive to add 🤣 we can both make useless comments it seems
Yeah I think hdcp and reprocessing would be most difficult. There are hdmi splitter devices like those used for coloured bias lighting that I think could be used….similarly I think the processing actually isn’t unsolvable, it’s not much different than object detection from a live camera stream. I agree re-encoding the stream would be too hardware intensive for anything “cheap” like a pi, hence the secondary device control alternative initially, but analyzing the stream should be possible.
Because I think this could be neat product……kinda like PiKVM, but maybe using ML to detect ads and make it a nice community tool to block in a device independent way. like hardware Adblock.
Yes. That’s what allows Unix legends like this: https://www.ee.torontomu.ca/~elf/hack/recovery.html
Seriously we did this in 1998, why this again??
It’s astounding. The same reason why the Steamdeck is better than the Asus and Lenovo imitation handhelds is why people will want the Apple Vision Pro compared to building your own headset and PC. Yet just because it’s Apple, all the edgelords are out in force refusing to see why a product combining existing technologies for you is better for the masses than one you cobble together yourself.
Didn’t we do this already back in the 90s with IE bundling??
I had a pi 1b running my hvac/humidifier/HRV unit at home for years. Only removed it when we moved out.
So I’m SUPPOSED to run a miner to keep mine from being overly idle??
I have 2 Pi 4s in operation. One is a Moonlight/USBoverIP stream gaming portal. It automatically turns on and connects to a VM running Sunshine on my Proxmox host, passes any USB controllers/bluetooth etc to the VM so the big loud gaming box is in the basement and the tiny Pi is next to the TV. 1080p60 works great, minimal lag.
The other acts mostly as a quorum server for the proxmox servers, I have two proxmox hosts and use the second Pi to ensure the cluster doesn’t get split brain. It also acts as a USBoverIP host for my home automation Zigbee and Zwave usb sticks, so that either proxmox host can connect to the USB sticks and the home automation VMs aren’t locked to a physical host.
The most annoying part I think is because I so rarely need them. All my Pis run headless, but the one time I do need direct console access I have to find the bloody adapters. Leaving them attached and unused is just asking them to get damaged.
Rather than using micro-hdmi (which hardly anything uses), stick a pair of usb-c DP ports instead if size is an issue. at least then I don’t need adapters that are ONLY needed for the Pi.
