Abstract
According to at least one embodiment, a method comprises observing communication from a virtual machine (VM) to a domain in which a device driver for a shared resource resides. The method further comprises determining, based on the observed communication, CPU utilization of the domain 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 domain in which a device driver for a shared resource resides, wherein the domain is operable to receive requests from the VMs for access to the shared resource. The system further comprises a CPU utilization monitor operable to determine an amount of CPU utilization of the domain in processing the received requests that is attributable to each of the VMs.
