Kemari starts synchronizing VMs when QEMU handles I/O requests.
Without this patch VCPU state is already proceeded before

We discussed moving the barrier to the actual output device, instead of
the I/O port. This allows you to complete the I/O transaction before
starting synchronization.
Does it not work for some reason?
Sorry, I've just started working on that.
I've posted this series to share what I have done so far.
Thanks for looking.
