Abstract:
A system and method of removing power from a device assigned to a virtual machine running on a host machine includes receiving a request, by a notification module, from the virtual machine to remove power from the device, and receiving, by the notification module, an indication from the virtual machine that a condition has been satisfied; managing an execution priority for requests, by a task module, where the task module schedules the request to be executed after the notification module receives the indication that the condition has been satisfied; and in response to execution of the request, by a power down module, sending a communication to the host machine to cause the host machine to remove power from the device.
