LiteGreen: Microsoft system to save desktop energy by virtualizing users’ desktop as virtual machine (VM)

A Microsoft research called “LiteGreen,” a system to save desktop energy by virtualizing the user’s desktop computing environment as a virtual machine and then migrating it between the user’s physical desktop machine and a VM server, depending on whether desktop computing environment is being actively used or is idle:

“To reduce energy wastage by idle desktop computers in enterprise environments, the typical approach is to put a computer to sleep during long idle periods (e.g., overnight), with a proxy employed to reduce user disruption by maintaining the computer’ network presence at some minimal level. However, the Achilles’ heel of the proxy-based approach is the inherent trade-off between the functionality of maintaining network presence and the complexity of application-specific customization.”

The 15-pages research paper, published by Microsoft Research India, DOCOMO US Labs and The University of Michigan is available here, or a low resolution video of LiteGreen prototype in action is embedded below:
