1. A method for capturing Central Processing Unit (CPU) utilization for a virtual machine, comprising: receiving, on a computer device, a work request having a set of jobs in the virtual machine from a host that hosts the virtual machine, wherein the work request is accompanied by an account identifier; creating a first account record for the work request via a first system call to the host that includes the account identifier, the first account record indicating at the host a beginning of the work request; processing, on the computer device, in response to the creating of the first account record, the work request in the virtual machine to complete the set of jobs; and creating a second account record for the work request in response to completion of the set of jobs via a second system call to the host that returns the account identifier and 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 process the work request from the first account record from a viewpoint of the host.
