Abstract:
A system and methods for migrating a virtual machine (VM). In one embodiment, a hypervisor receives a request to migrate the contents of a memory of a source VM in a first physical memory area to a destination VM in a second physical memory area, where the first and second physical memory areas are disjoint. The hypervisor executes the destination VM in response to the request, and detects an access of a page of memory of the destination VM. The hypervisor determines, in view of a data structure maintained by a guest operating system executing in the destination VM, that a first page of a memory of the source VM in the first physical memory area is currently in use by the destination VM. In response to the detecting, the hypervisor: copies, in view of the first page of VM memory being used by the destination VM, the contents of the first page to a corresponding page of the destination VM; and maps, in view of a second page of VM memory not being used by the destination VM, (i) a physical memory page that is external to the first physical memory area and to the second physical memory area to (ii) a page of the destination VM corresponding to the second page.

Claim (Index 9):
The method of  claim 1 , wherein mapping of (i) the one or more physical memory pages of the host computing system that are external to the memory of the source VM to (ii) the one or more memory pages of the destination VM that correspond to the one or more unused pages is performed instead of copying the one or more unused pages of memory of the source VM to the destination VM.
