A virtual machine deployment method and device

Abstract

The embodiments of the invention disclose a virtual machine disposition method and apparatus. The method comprises the following steps: receiving disposition request information of a virtual machine, wherein the disposition request information carries a first resource applied for by the virtual machine; according to the first resource of the virtual machine, determining a linearity correlation coefficient, similarity and a first Euclidean distance between each physical machine in a physical machine cluster and the virtual machine; according to the linearity correlation coefficient between the virtual machine and each physical machine, determining first weights of the virtual machine and each physical machine; according to the first Euclidean distance between the virtual machine and each physical machine, determining second weights of the virtual machine and each physical machine; and according to an object physical machine selection rule, the similarity, the first Euclidean distance, the first weights and the second weights, determining an object physical machine disposed to the virtual machine. It can be seen that when the object physical machine is selected, the disposition request information sent by the virtual machine carries N resources, such that the problem of load nonuniformity caused by single-attribute disposition or random disposition in the prior art is overcome.

Description

technical field [0001] The present invention relates to the field of data center resource scheduling, and more specifically, to a virtual machine deployment method and device. Background technique [0002] Cloud data centers provide users with infrastructure as a service (IaaS) through virtualization technology. Virtualization technology provides a good performance isolation guarantee for virtual machines, ensuring that virtual machines do not affect each other, thus allowing multiple virtual machines to run on one physical machine at the same time. Driven by demand, the number of virtual machines in the cloud will increase, and the deployment of virtual machines has become a new challenge: a simple random deployment strategy will cause the virtual machine to fail to select a suitable server, resulting in load imbalance; and At present, many virtual machine deployments often only consider the single attribute factor of CPU, but the deployment and scheduling strategy based o...
