基于资源特征匹配的虚拟机放置算法

Virtual machines placement algorithm based on resource utilization feature-matching

针对目前数据中心的资源低效利用问题,提出了一种基于资源消耗特征匹配的虚拟机放置算法VMP-RUFM(virtual machines placement algorithm based on resource utilization feature-matching)。算法在虚拟机应用的性能表现和访问模式两个层面上,建立虚拟机资源特征模型,进而选择资源消耗特征与物理机资源配置相匹配的虚拟机集合。实验结果表明,该算法对满足条件的虚拟机进行关联后,能够显著优化虚拟机整体资源消耗和对应物理机资源配置的匹配程度。

VMP-RUFM （virtual machines placement algorithm based on resource utilization feature-matching） is proposed to ad- dress the problem of resource inefficient utilization in data centers. Considering of the feature of performance and access mode of virtual machine application, the algorithm models feature expression of resource utilization. After that, the method selects the associated collection of virtual machines of which resource utilization feature matches the resource allocation of physical machine. The experimental results show that this approach can effectively optimize the matching degree between resource utilization of vir- tual machines and resource allocation of relevant physical machine.
