SYSTEM, METHOD AND PROGRAM TO MANAGE MEMORY OF A VIRTUAL MACHINE

摘要

Management of virtual memory allocated by a virtual machine control program to a plurality ofvirtualmachines. Each of the virtual machines has an allocation of virtual private memorydivided into working memory, cache memory and swap memory. The virtual machine control program determines that it needs additional virtual memory allocation, and in response, makes respective requests to the virtual machines to convert some of their respective working memory and/or cache memory to swap memory. At another time, the virtual machine control program determines that it needs less virtual memory allocation, and in response, makes respective requests to the virtual machines to convert some of their respective swap memory to working memory and/or cache memory.
