Some systems (e.g., VMs on qemu-0.13 with the default vcpu model) report an unsupported CPU model: Performance Events: unsupported p6 CPU model 2 no PMU driver, software events only. Subsequent invocations of perf fail with: The sys_perf_event_open() syscall returned with 19 (No such device) for event (cycles). /bin/dmesg may provide additional information. No CONFIG_PERF_EVENTS=y kernel support configured? Add ENODEV to the list of errno's to fallback to cpu-clock.
