Abstract:
Methods for providing shadow page tables that virtualize processor memory protection. In one embodiment, virtualization software maintains the following: (a) a mapping φ from guest domain identifier to a set of shadow L2 page tables that back guest L1 sections marked with a domain identifier; and (b) with each such shadow L2 page table, a set ω of back-pointers to “potentially referencing” shadow L1 descriptors.
