Hi, all. I got a new problem. When I use perf to get CPI( cycles per instruction) on a Virtual Machine, I receive the message that cycles and instructions are not supported.
However, other events like page-faults or context-switches can be supported well. I don't know why. So I guess I can't user perf to record a certain sort of performance events on Virtual Machine. Is my guess correct?? What kind of performance events in hell aren't supported? Thanks for all your help.
