The issue is that the engine DB backup you are going to restore already
contains a reference to the previous hosted-engine storage domain and to
the previous hosted-engine VM and so on and so the auto-import procedure to
have the engine VM looking up for its own infrastructure will not trigger.
You have to manually remove them form the DB you restored.
