19 -----------
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
29 is input, the perf data file name is perf.data.guest. If --host is input,
31 perf.data.host, please input --host --no-guest. The behaviors are shown as
33 Default('') -> perf.data.guest
34 --host -> perf.data.kvm
35 --guest -> perf.data.guest
36 --host --guest -> perf.data.kvm
37 --host --no-guest -> perf.data.host
45 'perf kvm buildid-list' to display the buildids found in a perf data file,
49 was captured with --guestmount in perf kvm record.
51 'perf kvm stat <command>' to run a command and gather performance counter
55 events are supported. 'perf kvm stat record <command>' records kvm events
56 and the events between start and end <command>.
57 And this command produces a file which contains tracing results of kvm
