A method and system for judging idle virtual machine and method for closing virtual machine

Abstract

The invention discloses a method and system for judging an idle virtual machine and a method for shutting down a virtual machine, which belong to the technical field of desktop virtualization, and include: S1, establishing a message statistics module in a virtualization data transmission protocol on a virtual machine server side; S2 1. Establish idle virtual machine detection service in the server; S3, call the message statistics module to detect whether the keyboard and mouse of the virtual machine are inactive for a long time; if so, perform step S4; S4, call the message statistics module to detect whether the screen image of the virtual machine is No change for a long time; if so, execute step S5; S5, call the message statistics module to detect whether the virtual machine has no voice activity for a long time; if so, mark the virtual machine as idle state. The present invention mainly solves the problem that the index for judging whether the virtual machine is in an idle state is relatively inaccurate. The present invention detects whether the keyboard and mouse of the virtual machine have been inactive for a long time, whether the screen image has not changed for a long time, and whether there has been no voice activity for a long time, and the judgment result more precise.

Description

technical field [0001] The invention relates to the technical field of desktop virtualization, in particular to a method and system for judging an idle virtual machine and a method for closing the virtual machine. Background technique [0002] Through virtualization technology, multiple virtual machines can be run on one computer to realize desktop virtualization, that is, Desktop Virtualization. [0003] One of the advantages of virtualization technology is elastic computing, that is, computing resources can be allocated reasonably according to the needs of each user. machine performance and optimize resource allocation. [0004] Many virtual machines will be in an idle state during certain periods of time, but the virtual machines in the idle state will still occupy CPU resources and memory resources, so that the server cannot allocate the occupied computing resources to the required virtual machines. Waste of electricity. In order to release the computing resources occ...

Problems solved by technology

[0005] The traditional indicators for judging whether a virtual machine or computer is in an idle state are whether the keyboard and mouse have not been operated for a long time, and further judge whether the utilization rate of CPU and memory is even. However, it is not accurate to use the above two indicators to judge an idle virtual machine

For example, when a virtual machine is playing a video or audio conference, the keyboard and mouse may not be operated for a long time, and the CPU and memory usage fluctuate less. At this time, the virtual machine is easily judged as idle, but the It is inaccurate that the virtual machine of the meeting is judged as idle
