Virtual machine resource allocation method and device and electronic device

Abstract

The invention provides a virtual machine resource allocation method and device and an electronic device. The virtual machine resource allocation method comprises the following steps: determining the type of a dominant resource of a physical machine cluster according to a virtual machine resource application request; determining the physical machines of which the types of the dominant resources arethe same as the types of the dominant resources of the physical machine cluster as candidate physical machines; and determining the candidate physical machine with the minimum occupation ratio of theresources with the type the same as that of the dominant resources as the target physical machine for creating the virtual machine on the target physical machine. According to the virtual machine resource allocation method and device and the electronic device provided by the invention, a large-specification virtual machine can be conveniently applied and created, different types of resources in asingle physical machine can be uniformly occupied, and the physical machine operation and maintenance risk of a user can be conveniently reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a virtual machine resource allocation method, device and electronic equipment. Background technique [0002] In the public cloud environment, users need to apply for creating virtual machines with different specifications according to their business. How to reasonably and efficiently allocate the resources of each physical machine in the physical machine cluster to create virtual machines has always been a challenge for the public cloud environment. [0003] The virtual machine resource allocation method in the prior art has at least the following defects: 1) The resource allocation is unreasonable, resulting in that although there are resources in the physical machine cluster, it is impossible to produce large-scale physical machine resources, that is, it is impossible to successfully apply for the creation of large-scale virtual machine resources. virtual machine. 2...

[0003] The virtual machine resource allocation method in the prior art has at least the following defects: 1) The resource allocation is unreasonable, resulting in that although there are resources in the physical machine cluster, it is impossible to produce large-scale physical machine resources, that is, it is impossible to successfully apply for the creation of large-scale virtual machine resources. virtual machine

2) The resource application of a single physical machine is unreasonable. For example, the Central Processing Unit (CPU) resources of a physical machine have been exhausted, but the memory (MEM) resources are still remaining, resulting in the remaining memory resources being unable to continue to be used

3) Multiple virtual machine resource application requests from a single user will fall on one physical machine, which increases the user's physical machine operation and maintenance risk
