Increasing the speed of qemu clock

Question

I'm trying to increase the speed at which qemu runs, so for example one tick of the real CPU will correspond to two ticks of the virtual time of qemu. Is this possible and if so does anyone have any pointers on how to go about doing this?

Answer 1

You can't do this. QEMU is not made for such thing.

QEMU does not simulate timing of execution. It doesn't know anything about CPU caches etc., so it can't be accurate even if it is desirable. It simply executes guest code, as fast as it can. No acceleration or deceleration.

At least do not seek solution this way.
