Abstract
According to an embodiment, a method of sampling hardware events in a computer system comprises a first step and iterative performance of second and third steps. In the first step, an initiator virtual machine identifies a profiling event and a count to a virtual machine monitor. The virtual machine monitor iteratively performs the second and third steps. In the second step, the virtual machine monitor programs a hardware event counter with the count for the profiling event. In the third step, upon receiving an interrupt from the hardware event counter, the virtual machine monitor saves a sample that comprises a code-in-execution identifier.
