A correction here. I'm not against propagate NaTpage attribute to machine TLB, and only claim that Xen can just respond per attribute what guest specified. No need to care whether page 0 is mapped specially. ;-)

Yes, that's what I meant to say - we can propagate the NaTpage attribute to the machine TLB, then we can simply reflect the NaT fault.

I think delivering a TLB miss is not sufficient. Because the mapping for the zero page is indeed in Linux's pagetable, the TLB miss handler succeeds in finding and inserting it, and the page fault handler is not triggered.
