Abstract
Official abstract text for this publication.
A system and method for display power management in a virtualized environment are disclosed. In accordance with one embodiment, a hypervisor that is executed by a first computer system receives a notification that a host operating system of a second computer system has received a command to dim a video display of the second computer system, and forwards the notification to a guest operating system of a virtual machine hosted by the first computer system. The hypervisor receives from the guest operating system a first signal that indicates that the hypervisor is to notify the host operating system to refrain from executing the command. The hypervisor then transmits a second signal that notifies the host operating system to refrain from executing the command.
