Method and system for hypervisor based power management

A system for hypervisor based power management in a virtualized environment, the system comprising:

• a first layer of hardware resources;
• a second layer including a hypervisor that virtualizes the hardware resources and provides an upper third layer with the appearance of multiple independent virtual machine partitions;
• a performance monitor in communication with the hypervisor, the performance monitor configured to observe the performance of the virtual machine partitions;
• a policy manager in communication with the hypervisor, the policy manager configured to allocate resources to the virtual machine partitions;
• a power metering component and a power control component configured within the hypervisor, the power metering component configured to track power consumption in the virtual machine partitions, and the power control component configured to scale power consumption rates of the virtual machine partitions based on the allocated resources;
• an I/O service partition in communication with the hypervisor;
• wherein the power metering component identifies virtual machine partitions that are sources of excessive power consumption based on a service level agreement (SLA);
• wherein the performance monitor compares the performance of the virtual machine partitions to the SLA;
• wherein the policy manager allocates resources based on the SLA;
• and
• wherein the hypervisor adjusts input/output share of the virtual machines with the I/O service partition.
