摘　　要：针对将基础设施作为服务的云计算平台中虚拟机部署问题,通过分析现有云计算平台的应用模式,建立了虚拟机部署模型,提出了一种快速资源匹配策略。该模型根据计算节点可用CPU个数和内存的大小将其划分到对应的二维容器队列中,然后再进行资源的匹配。在进行资源匹配时采用了计算单元优先匹配的策略,提高了计算节点CPU的利用率。将文中提出的虚拟机部署机制在基于Eucalyptus的开源云计算平台中实现。实验测试表明,该虚拟机部署机制实现了虚拟机的快速部署,提高了资源的利用率和部署效率。Aiming at the deployment of virtual machine of cloud computing platform,which provides infrastructures as a service, raise a model of deploying virtual machine based on analysis of existing application mode of cloud computing platform, and propose a strategy of matching resources fast. The model partitions all of computing nodes into the two-dimensional container queue based on the size of a- vailable CPU and available memory by monitoring computing node,and then matches the resources. In resource matching strategy,com- puting unit priority matching to improve the CPU utilization of the computing nodes. The virtual machine deployment mechanism which is presented is implemented in the open source cloud computing platform based on the Eucalyptus. The experimental results show that the mechanism of deploying virtual machine improves utilization of resource and the efficiency of deployment.
