Virtual machine management method and device, and storage medium

Abstract

The invention discloses a virtual machine management method and device, and a storage medium. The method comprises the following steps that: taking the resource factor of a physical machine as a sample characteristic, and taking the matching degree of the physical machine as a target variable to construct the sample of a corresponding physical machine; on the basis of a training set which comprises a plurality of samples, training a linear regression model; comparing the resource requirement of each dimension of a target virtual machine to be created with the resource of the corresponding dimension of a candidate physical machine; removing the candidate physical machine which does not meet the resource requirement of the target virtual machine on any one dimension; taking the resource factor of each dimension of the candidate physical machine as an input variable, inputting the resource factor into the linear regression model, and carrying out prediction to obtain the matching degree of the candidate physical machine; and according to the descending order of the matching degree of each candidate physical machine, selecting a host for creating a target virtual machine in the candidate physical machine. When the method is implemented to create the virtual machine, the virtual machine can own enough resources capable of finishing tasks, and the resource utilization efficiency of the physical machine is improved.

Description

technical field [0001] The present invention relates to computing technology, in particular to a virtual machine management method and device, and a storage medium. Background technique [0002] The continuous development of computer technology has laid the technical foundation for all walks of life to realize the needs of the industry through the creation of virtual machines. [0003] For example, according to actual needs, create virtual machines with various functions such as cloud computing, database and content distribution in physical machines (such as servers). [0004] In view of the fact that the operation of the virtual machine still depends on the resources of the physical machine, in related technologies, when selecting the physical machine for creating the virtual machine as the host machine of the virtual machine, the physical machine with the most resources is usually selected among the physical machines that meet the resource requirements of the virtual machi...

AI Technical Summary

Problems solved by technology

Although this method of creating a virtual machine can ensure that the virtual machine has enough resources to run normally, the remaining resources of the host machine cannot be fully utilized.

[0005] Assume that the virtual machine needs 2-core central processing unit (CPU) and memory with a storage space of 2 gigabytes (G) bytes, and virtual machine 2 needs 4-core CPU and 8G memory; the resource of A of candidate physical machine 1 is 2-core CPU , 8G memory, the resources of physical machine B are 4-core CPU and 4G memory; if the CPU requirements are met first and then the memory requirements are sorted, the greedy algorithm provided by related technologies will give priority to the physical machine with the most resources to run the virtual machine, That is, physical machine A is preferred as the host machine of the virtual machine. However, physical machine B can also meet the resource requirements of the virtual machine. If physical machine A is selected as the host machine, it will result in the need to create a virtual machine on physical machine A later. There are insufficient resources to create a new virtual machine, resulting in a waste of physical machine A resources

[0006] To sum up, there is no effective solution for how to create a virtual machine on a suitable physical machine so that the virtual machine has enough resources to run and improve the resource utilization efficiency of the physical machine.
