Hey, I'm the co-creator of LibVF.IO and the GVM project. I'd love to hear what you think about our latest release where we added support for GVM components in LibVF.IO.

Side note: We also added in support for Libvirt by allowing users to install standalone GVM components via ./scripts/install-standalone-gvm-components.sh.

To be honest with you I am extremely excited by what you are working towards, but utterly beyond confusion when it comes to the GPU virtualization landscape. The walls that vendors have built in this area in their attempt to artificially segment "consumer" and "professional" are shameful. NVidia in particular has been reprehensible. I wish more people cared. Thank you!

What does it do? Does it let one pass a virtual GPU to the guest without complete PCI-passthrough? E.g. will I be able to share host GPU between the host system and guests?

Ya, that's exactly correct. :)

GPU can not even run its own OS basically, it's a parallel co-processor, when-should/how-could I use it as a VM?

This is pretty cool, one of the killer features that windows has had with Hyper-V that is really creaming QEMU/KVM. You could probably try getting some support from a vendor like Red Hat, as something like this in the Linux Kernel is a huge datacenter/cloud hosting feature that directly impacts their bottom line.

Thanks for your kind words! We're all virtualization users ourselves so I definitely get what you mean - we started this project because we wanted to help people to get access to the magic at home using the hardware they already have! I will say though that Nvidia has done a lot towards improving their support for open source. While it might be a bit of an uncommon take in my view many of the folks who probably are most passionate about bringing exciting GPU technology to the world work at Nvidia. :)

According to https://docs.linux-gvm.org/

"GVM ... may be used in combination with KVM or other platform hypervisors such as Xen* to provide a complete virtualization solution via both central processing (CPU) and graphics processing (GPU) hardware acceleration."

I would love to work with folks like the people at RedHat! We're working on some new tools in C (GPLv2) which we think will make it easier to work with existing kernel/driver maintainers. We'll announce some of those things early next month and right after we'll be at QubesOS Summit & KVM Forum. I hope we get the opportunity to talk to some of the RedHat folks! :)
