[Users] Updating AIO from 3.3.4 to 3.4

Hello, I know that AIO setup is only for experimenting and trying but I find it very useful in several situations. So having a 3.3.4 All-In_one installation on fedora19 and wanting to update it to 3.4 I have some doubts. In release notes I see for general updates: On Fedora 19 you'll need to enable fedora-updates repository for having updated openstack packages --> OK. It is normally already enabled On Fedora 19, you'll need to enable fedora-virt-preview repository for using Fedora 19 as node on 3.4 clusters --> how do I managed this? This is indeed a node too, so I have to enable virt-preview for it? Correct? BTW: Is this note still true in general or did the related virt packages go into fedora-updates, or is it planned in coming days/weeks? When engine-setup is run and detects that a newer version is available and outputs that I have to run yum update ovirt-engine-setup is it correct to say that in AIO setups I should actually run yum update ovirt-engine-setup ovirt-engine-setup-plugin-allinone or is it the latest package not crucial to be updated before new engine-setup is run? At the end of engine update can I simply put the AIO server into maintenance (as a node) and run "yum update" so that vdsm (aka node) packages are updated too and so the server will become a 3.4 enabled node after reboot? Thanks, Gianluca
