With that, I would assume KVM itself would drive the live update and
would make LUO calls to preserve the resources in an orderly fashion
and then restore them in the same order during boot.

I don't think so, it should always be sequenced by userspace, and KVM
is not the thing linked to VFIO or IOMMUFD, that's backwards.
