Any given page is either a domheap page or a xenheap page, so there is no mapping in the sense you seem to be thinking of.

So , the domheap pages and xenheap pages are both controled by xen? The guest pages can be mapped to domheap pages and we can monitor these pages in xen hypervisor to see the content of guest pages?

And sorry for the type error.I mean in HVM doms with EPT supported, is there any difference if I want monitor guest domains memory regions in xen hypervisor? Maybe the functions which translate guest virtual address to xen virtual address.
