  • Opportunistic page caching for virtualized servers
    Patent number: 9110806
    Abstract: A system described herein includes a receiver component that receives an indication that at least one page in virtual memory is free and the at least one page in virtual memory is classified as short-lived memory, wherein the virtual memory is accessible to at least one virtual machine executing on a computing device. The system also includes a cache updater component that dynamically updates a cache to include the at least one page, wherein the cache is accessible to the at least one virtual machine.
    Type: Grant
    Filed: March 10, 2010
    Date of Patent: August 18, 2015

  • Virtual machine memory management in systems with asymmetric memory
    Patent number: 9009384
    Abstract: A system is described herein that includes a predictor component that predicts accesses to portions of asymmetric memory pools in a computing system by a virtual machine, wherein the asymmetric memory pools comprise a first memory and a second memory, and wherein performance characteristics of the first memory are non-identical to performance of the second memory. The system also includes a memory management system that allocates portions of the first memory to the virtual machine based at least in part upon the accesses to the asymmetric memory pools predicted by the predictor component.

  • Managing performance interference effects on cloud computing servers
    Patent number: 8464255
    Abstract: A method described herein includes an act of receiving indications of threshold levels of quality of service to maintain for each of a plurality of virtual machines sharing computing resources on a server, wherein quality of service is affected by interference caused by the plurality of virtual machines sharing the computing resources on the server. The method also includes an act of dynamically allocating computing resources amongst the plurality of virtual machines to maintain levels of quality of service for each of the plurality of virtual machines at or above the threshold levels of quality of service.
