You forgot to describe how you tested it? Does it actually work.
And why do you want to do it it? What's the use case?

The general understanding was that it doesn't work very well on a real
machine at least because it cannot be controlled how that memory maps
to real pluggable hardware (and you cannot completely empty a node at runtime)
and a Hypervisor would likely use different interfaces anyways.
