Virtual machine management method and device

Abstract

The invention provides a virtual machine management method and device. The method comprises the following steps: obtaining the identification information of at least one virtual machine used for deploying a target application; according to the identification information of each virtual machine, creating a virtual machine monitoring node independently corresponding to each virtual machine; and independently utilizing each virtual machine monitoring node to obtain an amount of tasks which are operated in each virtual machine at present, and when the amount of tasks which are operated under at least one first target virtual machine is operated at present is zero, sending the identification information of each first target virtual machine to an external cloud management center to cause the external cloud management center to release each first target virtual machine. Through the technical scheme of the invention, a phenomenon that the task which corresponds to the target application is operated at present in the recovered virtual machine can be avoided, and the normal operation of the target application can not be affected.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a virtual machine management method and device. Background technique [0002] In order to meet the business needs of different users, the cloud computing center needs to provide corresponding resource expansion and resource release functions, that is, to allocate virtual machines for target applications and release virtual machines that have been allocated to target applications. [0003] At present, the trigger conditions for resource expansion and release are mainly set in advance by the virtual machine hardware resource consumption threshold corresponding to the target application. After the cloud computing center allocates a corresponding number of virtual machines for the target application, the hardware Resource consumption rate, when the average hardware resource consumption rate of each virtual machine reaches the preset threshold, a virtual machine ...

Problems solved by technology

[0004] However, in the above technical solution, when the virtual machine is recovered according to the consumption of virtual machine hardware resources, there is no guarantee that there are no running tasks in the recovered virtual machine, and the virtual machine that is running the corresponding task is rashly recovered, triggering task interruption, and the Will affect the normal operation of the target application
