Method and System for Throttling a Processor Based on a Utilization Requirement of a Virtual Partition of the Processor

Disclosed is a method for throttling one or more processors of a physical system based on a utilization requirement of a virtual partition executing on the one or more processors. The method includes identifying one or more processors executing a virtual partition. Further, the one or more processors identified are independently throttled based on the utilization requirement of the virtual partition. Thus, the utilization requirement of the virtual partition is maintained while throttling the one or more processors to reduce power consumption of the one or more processors.

The method and system utilizes a hypervisor for identifying one or more processors executing a virtual partition. The hypervisor is an intermediary between the virtual partition and the one or more processors. The hypervisor stores and manages mapping information regarding execution of the virtual partition on the one or more processors. Based on the mapping information, the one or more processors are throttled for maintaining the utilization requirement of the virtual partition.

Thus, the method disclosed maintains the utilization requirement of a virtual partition by throttling one or more processors executing the virtual partition and reduces power consumed by the one or more processors.
