Method and controller device for quality of service (QOS) caching in a virtualized environment

摘要

A method and controller device for sharing computing resources in a virtualized environment having a plurality of virtual machines. The method includes assigning a portion of the computing resources to the plurality of virtual machines. The method also includes leasing by a first virtual machine at least a portion of the assigned computing resources of at least one second virtual machine. The first virtual machine leases computing resources from the at least one second virtual machine when the first virtual machine needs additional computing resources and at least a portion of the assigned computing resources of the at least one second virtual machine are not being used by the at least one second virtual machine.

1. A method for sharing computing resources in a virtualized environment having a plurality of virtual machines, comprising:
assigning a portion of the computing resources to the plurality of virtual machines; and leasing by a first virtual machine at least a portion of the assigned computing resources of at least one second virtual machine, wherein the first virtual machine leases computing resources from the at least one second virtual machine when the first virtual machine needs additional computing resources and at least a portion of the assigned computing resources of the at least one second virtual machine are not being used by the at least one second virtual machine, wherein the computing resources include cache space available for use by at least one of the virtual machines, and wherein the first virtual machine leasing the cache space cannot make the leased cache space dirty cache space.
