Xen Project Hypervisor: Virtualization and Power Management are Coalescing into an Energy-Aware Hypervisor

Power management in the Xen Project Hypervisor historically targets server applications to improve power consumption and heat management in data centers reducing electricity and cooling costs. In the embedded space, the Xen Project Hypervisor faces very different applications, architectures and power-related requirements, which focus on battery life, heat, and size.

Although the same fundamental principles of power management apply, the power management infrastructure in the Xen Project Hypervisor requires new interfaces, methods, and policies tailored to embedded architectures and applications. This post recaps Xen Project power management, how the requirements change in the embedded space, and how this change may unite the hypervisor and power manager functions.
