In my VM the corresponding dmesg is:

[ 0.038086] Performance Events: unsupported p6 CPU model 61 no PMU driver, software events only.
[ 0.041031] Hierarchical SRCU implementation.
[ 0.046210] NMI watchdog: Perf event create on CPU 0 failed with -2
[ 0.046980] NMI watchdog: Perf NMI watchdog permanetely disabled
