Well without real perf counters it's semi-useless (might be misleading) but anyway here what I got so far - #2 - guest idles two minutes in shell prompt:
bash-3.00# opreport --session-dir=/mnt/usb/oprofile_idle/
CPU: CPU with timer interrupt, speed 0 MHz (estimated)
Profiling through timer interrupt
