  • Patent number: 7640543
    Abstract: Disclosed is a virtual machine monitor (VMM) that controls access to a page table hierarchy by a guest operating system (OS). For example, the guest operating system may operate as part of a virtual machine. Particularly, the virtual machine monitor obtains control of memory access transactions responsive to the guest operating system attempting to access the page table hierarchy. More particularly, when the guest operating system attempts to access a page table, control of memory access transactions is trapped to the virtual machine monitor.
