1. A method for capturing Central Processing Unit (CPU) utilization for a virtual machine, comprising: issuing, on a computer device, a first script to produce a first system call to a host in response to a work request having a set of jobs received by the virtual machine from the host that hosts the virtual machine; creating a first account record for the work request in response to the first script via the first system call to the host, the first account record indicating at the host a beginning of the work request; issuing, on the computer device, a second script to produce a second system call in response to completion of the set of jobs in the virtual machine; and creating a second account record for the work request in response to the second script via the second system call to the host that returns the CPU utilization, the second system call being of a same type with the first system call and having no intervening system calls of the same type, wherein the second account record indicates the CPU utilization for the virtual machine to complete the set of jobs from the first account record from a viewpoint of the host.
