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 13):
The apparatus of  claim 10 , wherein determining the one or more unused pages of the memory of the source VM comprises determine, in view of a data structure that maintains a used status of memory pages of the source VM, the one or more unused pages of the memory of the source VM.
