Abstract
Provided are optimizations to the memory virtualization model employed in a virtual machine environment. An opportunistic hypervisor page mapping process is used in order to utilize large memory pages in a virtual machine environment. Using these optimizations, physical memory is being virtualized for the virtual machine in a manner that allows the operating system (OS) running within the virtual machine to take real and full advantage of large physical memory pages.
