For desktop computers in enterprise environments, the typical approach is to put a computer to sleep during idle periods. A newly available LiteGreen virtualization saves energy by migrating between the user’s physical desktop and the virtual server, depending on whether the machine is active of idle. This interface migration ensures the desktop is “always on” and network connected, even while the physical machine is turned off (Das 2010). This transition between the physical desktop and server has produced energy savings of 72% compared to 32% with standard operating system power management (Das 2010).
