Nested page tables are very similar to real-mode shadow paging: both translate guest physical addresses to host physical addreses. In any case, the merge driver is oblivious to the paging method used, it works at the Linux pte level and relies on mmu notifiers to keep everything in sync. -- Any sufficiently difficult bug is indistinguishable from a feature. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
