Abstract
Power management commands from virtual machines (VMs) in a VM environment may be trapped by a VM monitor. Depending on the current power states of the other VMs in the VM environment, the VMM may emulate increase or decrease in available resources as applied to the VM issuing the power management commands. The VMM may modify the actual hardware resources available in a platform when such modification may not affect the current power states of the VMs in the VM environment.
Claims10
A processor, comprising:
- hard-coded logic to execute a virtual machine monitor (VMM) to present a plurality of virtual machines to guest software, the plurality of virtual machines including a first virtual machine (VM) to issue a power management command to bring a computer system to a lower power mode, the virtual machine monitor to determine, in response to trapping the power management command and based on a global power management policy, whether to emulate a resource available to the first virtual machine and to emulate the resource in response to the determining.
