Kubevirt has some examples passing a vpgu into kvm https://kubevirt.io/user-guide/compute/host-devices/

Right, vGPUs are explicitly set up to generate BDF addresses that can be passed through (but require host driver support; they're essentially paravirtualized). I'm asking about MIG.

https://docs.nvidia.com/datacenter/tesla/mig-user-guide/supp... says GPU passhtrough is supported on MIG...

There's a MIG vGPU mode usable for this

Have you used it? How does it work? How do you drive it? We tried a lot of different things. Is it not paravirtualized, the way vGPUs are?

It works with SR-IOV instead of mdev afaik

Still needs some host SW to drive it but actually does static partitioning

IIRC it's usable through using the MIG-marked vGPU types
