What limits it to Nvidia? And is it using SR-IOV?

We do support other GPUs but currently that's through our LibVF.IO pathway (currently supports Nvidia, Intel, and some AMD GPUs):

A full list of supported devices is available here:

There are some limitations involved in LibVF.IO such as pre-defined mdev types. GVM is entirely free/libre open source software and it supports arbitrary mdev types. :)

We'll do our best to add more supported vendors to GVM/mdev-gpu in the near future.

Nvidia consumer cards like the 1060 can now be shared between host and VM? I though that was limited to datacenter cards and consumer cards must use exclusive PCI-E passthrough?

Ya, that works. :)

NVIDIA's vGPU technology has been cracked to work on most Maxwell and later devices. AMD and Intel have not been cracked and researched in the same ways.

Intel had GVT-g all the way up to 10th Gen Core, and then claim to have SR-IOV on some 11th Gen processors.

Yeah, that's what I suspected. I wish AMD would simply support SR-IOV normally.
