With Fedora 13, 2.6.33.5-112, vbox gives this message:

vboxdrv: Warning: 2.6.31+ kernel detected. Most likely the hardware 
performance
vboxdrv: counter framework which can generate NMIs is active. You have 
to prevent
vboxdrv: the usage of hardware performance counters by
vboxdrv:   echo 2 > /proc/sys/kernel/perf_counter_paranoid

But:

ls /proc/sys/kernel/perf*
/proc/sys/kernel/perf_event_max_sample_rate 
/proc/sys/kernel/perf_event_paranoid
/proc/sys/kernel/perf_event_mlock_kb

Is perf_counter_paranoid now perf_event_paranoid?
