Thanks in part to Jose's help I've gotten oprofile working on multiple domains with unstable. After reading the original Xenoprof paper, I have a question about how hypervisor samples are handled. If my understanding is correct, all samples pass through the hypervisor where they are then dispatched to the profiler in the corresponding domain. This makes sense in the case where code running in a given domain makes a hypercall. However, what happens when a hardware interrupt triggers code execution in the hypervisor? Where do such samples end up getting dispatched to and recorded? Thanks, David Carr _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
