  • VIRTUALIZING PHYSICAL MEMORY IN A VIRTUAL MACHINE SYSTEM
    Publication number: 20110087822
    Abstract: A processor including a virtualization system of the processor with a memory virtualization support system to map a reference to guest-physical memory made by guest software executable on a virtual machine which in turn is executable on a host machine in which the processor is operable to a reference to host-physical memory of the host machine.

  • Method and apparatus for a guest to access a memory mapped device
    Patent number: 7506121
    Abstract: Embodiments of apparatuses, methods, and systems for guests to access memory mapped devices are disclosed. In one embodiment, an apparatus includes evaluation logic and exit logic. The evaluation logic is to determine, in response to an attempt of a guest to access a device using a memory address mapped to the device and based on an access type, whether the access is allowed. The exit logic is to transfer control to a host if the evaluation logic determines that the access is not allowed.
