[Users] all-in-one: adding nodes, HA

Hi, I've been searching archives, but didn't find a definitive answers so decided to ask here. Question 1: all-in-one: adding nodes In case I use all-in-one installation, is it possible to add more nodes? I would be using shared iSCSI storage. What I understand, in order to use multiple physical servers, I need to dedicate one for management? Question 2: High Availability What I need to do in practice to get high availability between two virtual machines? I tried to search for guides. Do I need setup some watchdog devices and daemons? -Mr. Vesa Alho BTW, does Ovirt FAQ exists yet? My questions would be basic FAQ material. I can help out with Wiki if needed.
