If it was on purpose I would expect Sean (especially) to have called it out the subtle change in the commit message and probably add a comment here. Also I can't think of any reason why run_vcpus_while_disabling_dirty_logging=true would require dirty_log_manual_caps=0. Can you change this patch to just add a break and add a fixes tag to the commit message?
