We had this discussion before - the problem is not restricting the allocations
a domain does, but pages getting passed to it from other domains, which (if
they happen to lie outside the 166Gb range) the domain then can't control.
And yes, you said page flipping is basically dead, but this isn't being
enforced (and probably can't as long as you want to support older guests
potentially using it).
