Energy saving method, device and system under desktop virtual environment

Abstract

The embodiment of the invention discloses an energy saving method, an energy saving device and an energy saving system under a desktop virtual environment. The method comprises the following steps of: collecting specific event information corresponding to a virtual machine through a probe; determining a current state of the virtual machine associated with the specific event information according to the collected specific event information of the virtual machine and an acquired virtual machine idling strategy and outputting corresponding virtual machine state information to a management server, wherein the virtual machine state information indicates that the virtual machine is in an idle state or non-idle state; receiving a stand-by command transmitted by the management server and transmitting a corresponding stand-by instruction to a hardware layer to control a physical host of the virtual machine host to enter a stand-by state suspending to memory; and thus the phenomenon of network flow congestion caused by a great amount of heat transfer or load of the virtual machine is prevented while the energy saving effect is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of virtualization, and in particular, to an energy-saving method, device and system in a desktop virtualization environment. Background technique [0002] Virtualization technology makes it possible to install multiple different operating systems on a physical server and realize the isolation of each operating system. Even if an operating system or an application exception on an operating system is abnormal, it will not affect other operating systems. Virtualization technology sets up a layer of "Virtual Machine Monitor (Virtual Machine Monitor, VMM)" between the traditional operating system and physical hardware resources to realize the monitoring of physical hardware resources, such as processors, memory, storage, networks and other peripherals. Control and management of resources; the traditional operating system runs on the VMM and loses control and access to physical resources,...

Problems solved by technology

[0007] In the process of implementing the present invention, the inventor found that: in the existing scheme 1, in the desktop virtualization environment, when a large number of users need to use virtual machines at the same time (such as during rush hour), the physical host needs to load a large number of virtual machines from the storage network. Virtual machines can easily lead to network traffic congestion, and virtual machines start slowly or fail to start; and in the existing solution 2, the use of virtual machine resources is relatively stable, and the average resource load of physical hosts is relatively stable, so there are very few physical hosts that can be powered off. The energy-saving effect is not high; moreover, if a large number of virtual machine migrations will be triggered during the peak hours of work, a large number of "hot migration" will easily lead to network traffic congestion
