Abstract
A technique for accounting for resource usage time by virtual machines is provided according to which a virtual machine observes a non-virtual timer to determine an elapsed non-virtual time interval during which the virtual machine performed a computation while using a shared processing resource. The virtual machine infers the amount of time it used the shared processing resource based on the observation.
