Abstract
A method for tracking the changes to the emulated page tables of a host computer system is disclosed in which each memory location accessed by the guest computer system is placed on one of several hierarchical address translation lists maintained by the host computer system. In response to one or more events in the guest computer system, the contents of one or more of the address translation lists of the host computer system are unmapped as a means of tracking in the host computer system changes made to the address translation of virtual addresses to physical addresses in the emulated computer system.
