Nope, the patches are not currently upstream and we don't have any release
date.

Yes that's exactly this.

Finding someone with specific knowledge would be hard, i tried the vfio
mailing list 4days ago but didn't get any answer and they're pretty much
the only ones who will know this.
Actually i could remove everything from virt-preview if i knew what's
needed for libvirt to run, will probably end up doing this anyway but i
hoped for more insight, was a bit worry to break my system.
