Not likely, that would imply the system knew it was running in a virtual machine. You're not supposed to know you're in a virtual machine. I don't know who at IBM to ask about the hypervisor. As for oprofile, the oprofile list would be a start. Mark ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
