Hello Simone

The doubt is once one hosted engine is deployed to one of the hosts the
process to deploy in the second one is exactly the same or does it have any
minor particularity ? You mentioned that can be done via the web GUI. Do
you mean by cockpit or by oVirt Engine Web Interface itself ?

Thanks
Fernando
