No. qemu is not cycle accurate, and has no useful way of measuring effective
emulated CPU speed. A direct implication of this is that it is not meaningful
to try and regulate the "speed" of the emulated cpu.
You can of course use the facilities provided by your host OS to regulate the
amount of host CPU time qemu gets.
