System and method for attributing CPU usage of a virtual machine monitor to a corresponding virtual machine

摘要

According to at least one embodiment, a method comprises observing communication from a virtual machine (VM) to a virtual machine monitor (VMM). The method further comprises determining, based on the observed communication, CPU utilization of the VMM that is attributable to the VM. According to at least one embodiment, a system comprises a Central Processing Unit (CPU), Virtual Machines (VMs), and a Virtual Machine Monitor (VMM) operable to receive requests for resource access from the VMs. The system further comprises a CPU utilization monitor operable to determine an amount of CPU utilization of the VMM in processing the received requests that is attributable to each of the VMs.

1. A method comprising:
observing communication from a given virtual machine (VM) of a plurality of VMs, to a virtual machine monitor (VMM), by observing communication from said VM that is requesting access to a resource, as an access request for said VM by said VMM; and determining, based on said communication, utilization of the CPU by said VMM specifically attributable to said VM, and not attributable to any other of the plurality of VMs, wherein the utilization of the CPU by said VMM is the utilization of the CPU by said VMM performed for processing said access request for said VM by said VMM.
