The OP didn’t mention Proxmox in their post. I’ve been speaking generally, not about any specific OS. For example, Nvidia’s enterprise offerings include a license to use their “GRID” vGPU tech (and the enabled feature flag in the driver).

Why? Product segmentation I suppose. Last I looked, the Virtio project’s efforts were still work-in-progress. The Arch wiki article corroborates that today. Inconsistent behavior across brands and product lines.

I’ve also wanted to do this for a while, but there were always a few too many barriers to actually spin up the project. Here’s just a brain dump of things I’ve seen recently.

vGPUs continue to be behind a license. But there is now vgpu_unlock.

L1T just showed off PCIe “fabric” from Liqid that can switch physical devices between machines.

Turning VMs on and off isn’t as slick as either of the above, but that is doable today. You’ll just have to build all the switching automation yourself. That could just be a shell script running QEMU/libvirt commands, at a minimum.

Please inform yourself before diminishing others’ plights.

Diarrhoea that is characteristic of coeliac disease is chronic, sometimes pale, of large volume, and abnormally foul in odor. Abdominal pain, cramping, bloating with abdominal distension (thought to be the result of fermentative production of bowel gas), and mouth ulcers[35] may be present.

Coeliac disease leads to an increased risk of both adenocarcinoma and lymphoma of the small bowel

Long-standing and untreated disease may lead to other complications, such as ulcerative jejunitis (ulcer formation of the small bowel) and stricturing (narrowing as a result of scarring with obstruction of the bowel).
