Abstract
Efficient power management of a system with virtual machines is disclosed. In particular, such efficient power management may enable coordination of system-wide power changes with virtual machines. Additionally, such efficient power management may enable coherent power changes in a system with a virtual machine monitor. Furthermore, such efficient power management may enable dynamic control and communication of power state changes.
Claims20
A system comprising:
- a processor;
- one or more memories in communication with the processor when the system is operational, the one or more memories having stored thereon instructions that upon execution by the processor at least cause the system to:
- receive by a first virtual machine a notification of an impending system power change;
- in response to the notification, perform an action by the first virtual machine to prepare for the impending system power change;
- and
- forward, by the first virtual machine, a second notification to a second virtual machine.
A computer-readable storage device having stored thereon computer-readable instructions that upon execution on a processor, at least cause a computing device to:
- receive by a first virtual machine a notification of an impending system power change;
- in response to the notification, perform an action by the first virtual machine to prepare for the impending system power change;
- and
- forward, by the first virtual machine, a second notification to a second virtual machine.
A method for efficiently managing power used by one or more computing devices, comprising:
- receive by a first virtual machine a notification of an impending system power change;
- in response to the notification, perform an action by the first virtual machine to prepare for the impending system power change;
- and
- forward, by the first virtual machine, a second notification to a second virtual machine.
