Re: [Qemu-devel] [PATCH 1/5] single step with no IRQs and timers

[Fabrice Bellard <fabrice@bellard.org>]

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).
