Abstract

The invention discloses an automatic migration method of a virtual machine based on a cloud platform. The method comprises the following steps: determining the migration time of virtual machines according to the load of a host server; setting the weight according to the ratio of the resource usage on the host server and calculating the migration amount, and selecting the virtual machine with a larger migration value as a virtual machine to be migrated; and randomly selecting the migration target server of the virtual machine to be migrated according to the remaining resource on the host server and the probability value. The invention also relates to a system, comprising a migration time determination unit, a virtual machine to be migrated determination unit, and a migration target server determination unit. The automatic migration method and system disclosed by the invention have the effects that the load of the server is predicted by using an exponential smoothing method, and thus unnecessary migration overhead can be avoided; the target server is selected in a probability mode, so the clustering effect can be avoided; and the weight is set according to the usage of the resource during the entire process of migrating the virtual machines, and thus the operation bottlenecks of the cloud platform can be more easily discovered.

Description

technical field [0001] The invention relates to the field of cloud platform computing, and more particularly, to a method-level system for automatic migration of virtual machines based on an OpenStack cloud platform. Background technique [0002] Open1tack is currently the most mainstream open source cloud computing management platform project, which is composed of several main components to complete specific tasks. OpenStack supports almost all types of cloud environments, and the project goal is to provide a cloud computing management platform that is simple to implement, scalable, rich, and standardized. OpenStack provides an Infrastructure-as-a-Service (IaaS) solution through a variety of complementary services, each of which provides APIs for integration. [0003] During the operation of the OpenStack virtual machine, the stability of the physical host of the host is reduced due to the hardware limitations of the machine itself, excessive load and other reasons. Part ...
