    Abstract: According to one aspect of the invention, a request to generate a state checkpoint of a computer is initiated within a user-level software entity, such as a virtual machine. Upon sensing the request, a checkpointing mechanism generates and stores at least one checkpoint, each checkpoint comprising a representation of the total state of the computer system. Upon sensing a state restoration request corresponding to one of the checkpoints, the checkpointing mechanism restores the checkpointed state in the computer, which can then resume operation from the restored total state. According to another aspect of the invention, a total checkpointed state is exported to another computer, where the state can be modified, for example, debugged, and then loaded into either the originally checkpointed computer (which, again, may be a virtual machine), or some other computer.

    Abstract: A computing system includes a guest domain access control register (DACR), and guest first and second level page tables, the page tables containing domain identifiers used to obtain domain access information and access permission information, and the domain access information and the access permission information providing an effective guest access permission. The computing system provides a shadow page table, in which domain identifiers are used to identify domain access information in a processor DACR that are mapped from domain access information in the guest DACR, and in which access permissions are mapped from effective access permission information in the guest page tables and guest DACR. A memory management unit in the processor traverses the shadow page table, accesses the processor DACR, and combines the mapped domain access information in the processor with the mapped access permission in the shadow page table to reflect the guest intended effective access permissions.
