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.
