This will be a pretty major change.

QEMU 9.2 is now also being tested by Proxmox:
Did anyone try it out? Unfortunately no video encoding is supported by Virtio-GPU Venus yet. This means using it as a Gaming (headless) Server, Encoding server etc. will not work. But using it as an Compute VM might work.
@t.lamprecht Are there any params we can set in the VMs config to enable Venus, if we use QEMU 9.2?
For reference: I did use QEMU 9.2 locally. Running non-demanding Games like Northgard I could run one instance of it in a VM and one instance on the host at the same time with my RX 6800 flawlessly. Also more demanding Games like Metro Exodus or The Witcher III launch. They also do render with high FPS. But while Northgard was a really nice experience, there was still stutter in The Witcher and Metro. I guess there have to be some bottlenecks adressed in future qemu-releases on the virtio guest driver as well.
EDIT: Well, as far as I know you'll need Kernel 6.13 for it to work. So maybe we need to wait a little longer...

PVE 9 is based on Debian 13 Trixie and includes Trixie's repos.
It's got Mesa 25.
https://packages.debian.org/TRIXIE/libs/
Someone running the beta would need to confirm the exact version of Mesa in the available repos.
It's 25.0.7, as can be seen from https://packages.debian.org/search?searchon=sourcenames&keywords=mesa
Thanks, @t.lamprecht ! I admit that I have trouble navigating Debian's package listing site. It's weirdly intuitive, at least for me.
@DocMAX I'm sure several of us would be happy to help test this. Are there written directions somewhere for setting it up in Proxmox? I assume it's similar to the old VirGL setup.
Basically if virglrenderer + qemu + mesa is all updated to the current version it should work out of the box with VirGL driver (in the Proxmox GUI). You will have Vulkan available on (also current) Linux OSes (not Windows of course!)
Oh, good. I was hoping it'd be a drop-in replacement.
So, Venus completely replaces the old system in Mesa 25/VirGLrenderer? It's not possible to accidentally run the old version of VirGL? I'm very good at doing things accidentally.
VirGLrenderer is still the same exept "Venus" has been added to have OpenGL AND Vulkan working in you Linux-VM.
Can relate to that, I'm probably just visiting them more often and am used to them.
FWIW, maybe the tracker is more intuitive for you, it has also a lot of information, but some are grouped nicely, like the version information table on the left, that shows what version is in what suite (stable == current stable release, which is bookworm until trixie was officially released), see: https://tracker.debian.org/pkg/mesa
That's awesome! And yes, the tracker does seem easier to understand.
Debian's entire online aesthetic is very "cutting edge 2005 web site." That's not a criticism, but it definitely makes me feel like I'm going back in time.
