20 There are a couple of variants of perf kvm:
22   'perf kvm [options] top <command>' to generates and displays
26   'perf kvm record <command>' to record the performance counter profile
28   default behavior of perf kvm as --guest, so if neither --host nor --guest
30   the perf data file name is perf.data.kvm. If you want to record data into
34     --host              ->  perf.data.kvm
