Abstract

The invention discloses a virtual machine placing method and a virtual machine placing device. The virtual machine placing method comprises the following steps: according to established energy consumption models of physical servers, respectively acquiring the total energy consumption of the physical servers in a resource set within a preset time; establishing space constraint relations and time constraint relations of a virtual machine required to be placed to the physical servers, and acquiring total energy consumption objective functions; through a two-dimensional particle algorithm, according to the total energy consumption objective functions of the physical servers in the resource set, within each resource allocation, acquiring an objective physical server capable of optimally placing the virtual machine and meeting the established space constraint relations and the established time constraint relations, and energy consumption information thereof. Through the virtual machine placing method and the virtual machine placing device, while considering space attributes of the resources, time attributes of the virtual machine and the physical servers are comprehensively considered, and the overall energy consumption generated in each placement strategy is calculated, thereby achieving an aim of optimizing the energy consumption of the resource set, better avoiding the resource waste of the physical servers on the premise of meeting the space constraints of the physical servers, and thereby effectively reducing the energy consumption of a cloud data center.

Description

technical field [0001] The invention relates to cloud computing technology, in particular to a virtual machine placement method and device. Background technique [0002] At present, most of the methods to solve the energy-saving problem of cloud data centers, that is, resource sets, aim to reduce the number of physical servers used in cloud data centers, rationally formulate resource mapping strategies from virtual machines (VM) to physical servers (PM), and realize cloud data centers. energy consumption optimization. There are mainly two energy-saving virtual machine placement methods: the resource capability normalization method and the multi-dimensional bin packing algorithm. in, [0003] The resource capability normalization method, when formulating the placement strategy of the virtual machine to the physical server, firstly, the capabilities of the virtual machine and the physical server are simplified into one-dimensional indicators; then, the set of virtual machine...
