Abstract
Embodiments of systems, apparatuses, and methods for performing guest logical memory address to host physical memory address translation are described. In some embodiments, a system receives the guest logical memory address and determines an index page reference from the guest logical memory address. The system further retrieves a page index corresponding to the virtual machine. In addition, the system retrieves a first part of the host physical memory address from index page using the page index and a second part of the host physical memory address from the guest logical memory address. The system generates the host physical memory address from the first and second parts of the host physical memory address.
