초록

An embodiment of a method of virtualizing a counter in a computer system comprises a first step and iterative performance of second through fifth steps. In the first step, a virtual machine monitor programs a hardware event counter with an initial count for a profiling event for a virtual machine. In the second step, the virtual machine monitor saves a suspension count and disables the hardware event counter upon suspending operation of the virtual machine. In the third step, the virtual machine monitor programs the hardware event counter with the suspen...

청구항

What is claimed is: 1. A method of virtualizing a counter in a computer system comprising the steps of: a virtual machine monitor: programming a hardware event counter with an initial count which is a specific count number that must be reached before the hardware event counter generates an interrupt for a profiling event for a virtual machine; and iteratively performing the steps of: using a virtual machine monitor to suspend operation of the virtual machine while processor time and memory space is allocated to another virtual machine, and upon suspendi...
