Virtual machine cluster deployment algorithm

Abstract

The present invention relates to the technical field of cloud computing, and in particular to a virtual machine cluster deployment algorithm. The virtual machine cluster deployment algorithm comprises the steps of: analyzing a resource type of a cluster; filtering out a request that cannot be met; creating a priority queue; cyclically traversing all physical machines, and calculating a load coefficient L of each physical machine, and determining whether the physical machine can be selected as a deployment node; calculating a load value of each physical machine according to the resource type of the cluster, inserting the load value into the priority queue, and sorting elements of the priority queue in descending order of the load values; performing virtual machine mirror image transmission one by one in an order of the queue; and starting all virtual machines of the cluster, so as to complete cluster deployment. The present invention realizes a cluster deployment algorithm based on load value calculation; and the algorithm can be used for virtual machine cluster deployment.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a virtual machine cluster deployment algorithm. Background technique [0002] Due to the convenience of cloud computing technology, there are more and more applications on the cloud platform. Many enterprise users also need to deploy and create large-scale application clusters. The traditional virtual cluster deployment algorithm is only based on the utilization of a certain resource on the physical machine. The following problems exist in the planning of cluster deployment based on the rate: [0003] 1. The resource characteristics of the cluster are not fully analyzed, and various resources of the computer cannot be fully utilized; [0004] 2. The resource loss caused by image copying is not considered, and the copying process easily affects the performance of existing virtual machines.
