Performance analysis of guest VM´s on xen hypervisor

A virtual machine (VM) has access only a portion of computer resources but that appears to be a whole computer. Virtual machines are running on the same computer system hardware. The performance of the virtual machines are depends on the performance of the host operating system on which they are running. In this work the performance of different guest VM´s on the same host operating system has been analyzed. For this experimentation Ubuntu (Linux based operating system) is used as host operating system and Ubuntu as well as CentOS operating systems are used as guest operating system. Performance measurement of the virtual machines is done in the same conditions for both guest operating systems using different benchmark. In this work the performance of different guest VM has been analyzed using SysBench on CPU performance, Mutual Exclusion, Threads and Online Transaction Processing Test performance parameters. Results shows that for CPU Performance and mutex, CentOS 6.3 gives better results and for OLTP and Threads performance test Ubuntu performs well.
