[ovirt-users] no hosted engine deploy while adding new host (oVirt 4.3.5)

I tryed to add a new host to my oVirt environment. I remember a checkbox whether the engine HA wil depoyed or not in oVirt 4.1. Now the environmentist oVirt 4.3.5. In the add host dialog windows I cant find that option anymore. In edit window after host installation ther ist also no hosted engine tab. hosted-engine --deploy don't ask, if it is an additional host (like it used to in 4.1), so it will install a new engine instead of depoying the existing engine. Is there a new way of depoying the engine HA to additional hosts?
