METHOD AND APPARATUS FOR CACHING OF PAGE TRANSLATIONS FOR VIRTUAL MACHINES
摘要:
A method for caching of page translations for virtual machines includes managing a number of virtual machines using a guest page table of a guest operating system, which provides a first translation from a guest-virtual memory address to a first guest-physical memory address or an invalid entry, and a host page table of a host operating system, which provides a second translation from the first guest-physical memory address to a host-physical memory address or an invalid entry, and managing a cache page table, wherein the cache page table selectively provides a third translation from the guest-virtual memory address to the host-physical memory address, a second guest-physical memory address or an invalid entry.
