Comparative study on Virtual Machine Monitors for cloud

Cloud Computing is the distributed architecture in which scalable resources are used to provide computing services to user using virtualization concept. Cloud requires virtual machine for accessing any guest operating system at local desktop, this is handled by software interface such as Virtual Machine Monitor (VMM) or hypervisor. This paper reveals not only its features architecture, working but also comparative analysis of Kernel Virtual Machine (KVM) and Xen using various benchmarking tools. Paper also explains test analysis of measuring CPU performance, network speed and disk access. From this analysis which hypervisor has to be used for the implementation of cloud computing system for getting better performance is decided.
