This paper examines the virtualization of physical host machines, enterprise services, and multi-site instantiation of virtual environments. First, we introduce the difficulty of virtualizing enterprise service host machine. Second, we discuss use cases that can give IT organizations many new options in supporting their company's business units. Third, we review a case study of server virtualization for a business group at Intel and the process they followed from project inception through implementation. We conclude the paper with a discussion of our results and a description of the future work.
