云环境下虚拟机管理研究综述

A Survey of Virtual Machine Management in Cloud Environment

当云数据中心的用户大量涌入时,如何有效地管理数据中心的硬件资源和虚拟机,以降低经济成本,保证高质量的服务成为云提供商不可避免的工作。云计算提供商能够提供快速有效服务的重要保障是云数据中心的虚拟资源管理,而目前云数据中心资源管理的主要研究方向是虚拟机管理。本文先对虚拟资源相关研究进行了分析,讨论了云数据中心虚拟机布局的调度方法,总结了虚拟机动态迁移技术所面临的三大挑战、虚拟机迁移的三种分类方法以及虚拟机整合技术。最后,分析了未来云数据中心虚拟机管理的研究方向,希望能为后面的云数据中心虚拟机管理及研究提供一定的参考。

With a large number of cloud data center users rushing,it how to effectively manage the hardware resources and virtual machines of the data center to reduce the economic cost and ensure high-quality service becomes an inevitable task for cloud providers that how to effectively manage the hardware resources and virtual machines of the data center to reduce the economic cost and ensure high-quality service.The important guarantee for cloud computing providers to provide fast and effective services is the virtual resource management of cloud data center.At present,the main research direction of cloud data center resource management is virtual machine management.Firstly,this article analyzes the related research of virtual resources.Then it discusses the scheduling method of virtual machine layout in cloud data center.It also summarizes the three challenges which faced by virtual machine dynamic migration technology,three classification methods of virtual machine migration and virtual machine integration technology.Finally,the writer analyzes the future research direction of virtual machine management in cloud data center.It is hoped to provide some reference for the later virtual machine management and research in cloud data center.
