There's a subtle issue with option parsing in perf record. It calls the function with PARSE_OPT_STOP_AT_NON_OPTION so that it can pass later options to the external command it runs. But perf kvm record passes the default arch events after the argv. So if user calls it with command, then it passes the event to the external command and fails it like below: $ sudo perf kvm --host record sleep 1 sleep: invalid option -- 'e' Try 'sleep --help' for more information. [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.046 MB perf.data.kvm (5 samples) ] We can check if the default options are needed before passing the extra command line to make sure it's passed to perf record.
