An Evaluation of KVM for Use in Cloud Computing M.FENN,M.A.MURPHY,J.MARTIN,and S.GOASGUEN Clemson University In this paper we describe a virtual cluster based on the Kernel-based Virtual Machine(KVM as an alternative to VMWare and Xen.Speci cally we show how the virtual cluster is built and tailored to t virtual organizations.The technique presented in this paper,known as the Virtual Organization Cluster Model,shows great potential for cloud computing.In our implementation, we used a minimalist installation of Slackware Linux12on14compute nodes,ensuring minimal host overhead.Our prototype Virtual Organization Cluster is composed of28virtual computes nodes,each running CentOS5.1with Condor,and MPI.Results of testing the prototype were encouraging,with the exception of network performance.

Smaller research groups may not be able to a ord to have their own clusters,and purchasing time on an existing cluster raises concerns such as vendor lock-in and data security.
