That implies the protection hardware is not controlled by the dom0 and
there is another more secure way for the administration of it and second
that the dom0 can't do anything.
The dom0 can afaik do basically anything, so it also can claim "i'm
secure domU No. 2 and i want my data!", furthermore the dom0 should also be
able to overwrite the xen kernel.

Does not matter, it has the same latency, you'll get 10-20 MB/s memory
