  • Hardware protection of virtual machine monitor runtime integrity watcher
    Patent number: 10303503
    Abstract: An apparatus and method for hardware protection of a virtual machine monitor (VMM) runtime integrity watcher is described. A set of one or more hardware range registers that protect a contiguous memory space that is to store the VMM runtime integrity watcher. The set of hardware range registers are to protect the VMM runtime integrity watcher from being modified when loaded into the contiguous memory space. The VMM runtime integrity watcher, when executed, performs an integrity check on a VMM during runtime of the VMM.
    Type: Grant

  • Method, apparatus and system for limiting access to virtualization information in a memory
    Patent number: 8893124
    Abstract: Techniques for limiting access to virtualization information which is stored in a memory region allocated to a virtual machine instance. In an embodiment, virtualization information is written over in response to an indication of a close event which is to change an allocation of the memory region to the virtual machine instance. In another embodiment, the virtualization information is written over before the memory region is made available for a subsequent allocation.
