qemu doesn't maintain virtual time, it just uses the real host time. > I just tried with cpu_disable_ticks() and cpu_enable_ticks().

I suspect you'll find that for anything other than very coarse user (ie. user stop/continue) these are effectively useless. Any benchmark/performance measurements you make inside qemu are meaningless. qemu performance bears no relation whatsoever to the performance characteristics of real hardware.
