Hi, one of the new features of oVirt 4.2 is support for Replica 1 all in one setup using hosted engine and gluster in hyper-converged mode. So it should be again possible to use just a single host for everything, I am not sure we have a documentation ready for that though.

Re: [ovirt-users] Regarding Ovirt Installation
Hi, if you bought a dedicated server with virtualization extensions enabled you should have no problems. Ask your provider if that extension is enabled. A friend of mine on hetzner is using KVM without issues, but required some tweaks about network that you can find in their docs.
