Problems solved by technology

[0005] It can be foreseen that the processing method in the prior art is to create as many timers as there are virtual machines in batches. This method causes a waste of system memory resources. Timer, resulting in a sudden system cpu consumption in a short period of time is very large

Abstract

The invention discloses a method and a device for creating a timer for a virtual machine on the basis of thin provisioning, can save system memory resources and simultaneously can avoid the problem of large system CPU (Central Processing Unit) consumption burst in short time. The method comprises the following steps: S1) creating the timer, wherein the fixed time interval time of the timer is T, and the timer is provided with a task which carries out disk space detection on at least one virtual machine in a plurality of virtual machines created on batch in advance; S2) adding a detection task of the disk space of at least one virtual machine into the latest timer each time until the execution time of the latest timer is not smaller than a preset numerical value; and S3) judging whether the detection tasks of the disk spaces of a plurality of virtual machines finish being distributed in the created timer or not, and repeatedly executing S1 and S2 if the detection tasks of the disk spaces of the plurality of virtual machines do not finish being distributed until the detection tasks of the disk spaces of the virtual machines finish being distributed in the created timer.

Description

technical field [0001] The invention relates to the technical field of virtual machines, in particular to a method and device for creating timers for virtual machines based on thin provisioning. Background technique [0002] Thin provisioning is usually one of the means of virtualization technology, and is often used in the disk management of virtual machines. For example, a virtual machine is allocated a 100G disk when it is created. But the operating system in the virtual machine still thinks that there is still a 100G disk), when the disk is almost full of 10G, the thin provisioning program will apply for disk space for the virtual machine (for example, apply for 20G), so that the disk space can be increased little by little , and finally allocate 100G space for the virtual machine. [0003] Since no complete disk space is allocated once when the virtual machine is created, and it is necessary to dynamically apply for disk space for the virtual machine when the virtual m...
