Host virtualization has become of great interest as it is a technology that can enable the implementation of cloud computing. For this, it can offer several benefits, such as high levels of sharing of computing resources, ubiquitous availability, and savings on hardware investment. Although it has been claimed that host virtualization can also offer the benefit of energy savings, the levels of savings are unknown. In this paper, the authors present experimental evaluations of energy expenditure of virtual machines used for computation processes.
