[vfio-users] Hyper-v enlightments on recent NVIDIA drivers?

On the libvirt side, reading the documentation again i bumped into this :

      <vendor_id state='on' value='KVM Hv'/>


https://libvirt.org/formatdomain.html#elementsFeatures

Anybody knowing why we have to rely on qemu since apparently libvirt is
suppose to support this since 2012 ?

I have to admit i'm curious.
