Just to add an example why I think this "internal review" is a bad idea
I seem to recall that someone internal to nvidia at some point
attempted to implement this already. The only output from that
work we have is that "it's tough" - no pointers to what's tough,
no code to study even as a bad path to follow.
And while Red Hat might be big, the virt team is rather smaller.
