In the SVM case this still leaves the problem that the MSR bitmap must

This is easily solved by shadowing the MSR bitmap. Too bad we have to
do it, but at least the state isn't hidden in a non-extractable field
inside the processor.
We could write-protect the bitmaps and shadow them lazily when changed
(which should be never; also improves vmentry time). Write protecting
is bad since it breaks up large pages, but is necessary for exposing npt
to the guest, which is needed for reasonable performance, so we may as
well do it.
