I'd be curios to try vGpu with Qubes. It's definitely a security issue and has been left behind on newer NV consumer hardware but would be neat for low-risk qubes. I do have to admit that the performance is still great w/o hardware acceleration.

An old AMD workstation GPU supported SR-IOV partitioning, https://open-iov.org/index.php/GPU_Support#AMD

> It's definitely a security issue

Have there been public exploits of Intel or Nvidia SR-IOV implementations, to identify where hardening is needed?

Not that I’ve seen or heard of but my assumption is that it is mainly due to the relative rarity of partial/vgpu offerings outside of organizations. (Other than Blender render farming and some smaller upstart p2p gpu time reselling.)

I’d say Intel’s 12th gen igpu has “best supported” consumer vGpu offerings available and it’s through sr-ion I believe as well. I’ve had it on the back burner on my homelab until a recent performant gui need had come up.
