A method for oversubscribing a host memory of a host running a virtual machine monitor (VMM), comprising, examining a virtual machine (VM) memory for a VM for metadata associated with the VM memory, the metadata maintained by a guest OS running on the VM, collecting the metadata for the VM memory, and managing the VM memory using the metadata for oversubscribing a host memory.

Method and system for memory oversubscription for virtual machines

A method and system manages memory in a network of virtual machines, including a copy of a master virtual machine (VM) memory system, the copy accessible to a memory server. The method includes determining whether a memory page requested by a clone VM memory system is fetchable from the memory server, the clone VM memory system hosted in a host memory system; if the memory page is fetchable from the memory server, fetching the memory page from the memory server; determining whether there is sufficient space in the host memory system to load the memory page; if there is insufficient space in the host memory system, evicting a selected memory page from the host memory system; and loading the memory page into the host memory system and the clone VM memory system.
