Virtualization is a framework of dividing the resources of a computer into multiple execution environments. More specific it is a layer of software that provides the illusion of a real machine to multiple instances of virtual machines. Virtualization offers a lot of benefits including flexibility, security, ease to configuration and management, reduction of cost and so forth, but at the same time it also brings a certain degree of performance overhead. Furthermore, Virtual Machine Monitor (VMM) is the core component of virtual machine (VM) system and its effectiveness greatly impacts the performance of whole system. In this paper, we measure and analyze the performance of two virtual machine monitors VMware and VirtualBox using LMbench and IOzone, and provide a quantitative and qualitative comparison of both virtual machine monitors.
