Ya, that's exactly correct. :)

What about one GPU with multiple VM?

Annoying t hing right now is that you have to pony up for the fancy nvidia cards plus insane nvidia licensing for their multiGPU virtualized cards. AMD at least makes you only pay for the hardware but its still super pricey.

Ya, you can use multiple VMs. Here is a video I took of a laptop with LibVF.IO and an early pre-release version of GVM installed - at the start of the video you can see a fullscreen Windows VM and then I back out and open another compartmentalized 'app VM' (browser):

Both VMs are actually based on Windows (one simply doesn't have explorer.exe running) and each has it's own virtual GPU attached.

This laptop has a Nvidia graphics processor inside but it also works with laptops that have an Xe Intel graphics processor. I'm hoping at some point it will work well on AMD too.

Sounds very interesting! Do VMs work with a display session (Xorg) too?

Some GPU-enabled applications require an X server with a physical HDMI/Displayport attached.

Ya! You can use VMs that use X11 in the guest without issue. X11 also works on the host. Wayland is also working on the host - I haven't tested yet with Wayland guests yet so that's something to try.

Can I run CUDA in the guest OS (Windows)?
