Hi,
I agree that the feature is useful, but I am not sure yet if I will
apply as is. I am adding support in QEMU for deterministic execution and
your patch won't be needed once this new feature is released.
BTW, why do you stop real time timers ? These timers are only used for
things which do not interfere with the VM (such as VGA refresh).
Fabrice.
