Ok. I can't explain it. There's no special treatment for guest stack pages. The accessed bit should be maintained for them exactly like all other pages.

Are they kernel-mode stack pages, or user-mode stack pages (the difference being that kernel mode stack pages are accessed through large ptes, whereas user mode stack pages are accessed through normal ptes).
