Hi, please see below for more details.
tl; dr; Live merge works on oVirt-3.5.0 with Fedora 20 hosts that are using qemu and libvirt packages from the virt-preview repo. No other configuration is supported yet. We aim to have support for RHEL7.1 and later and built-in support for Fedora 21.
Sorry... pressed return too quick..
Understand me, please. My note was about Release Notes page misleading in respect with features' set and newcomers... but also frequent users too
At http://www.ovirt.org/OVirt_3.5_Release_Notes#Live_Merge ones reads:
" Live Merge If an image has one or more snapshots, oVirt 3.5's merge command will combine the data of one volume into another. Live merges can be performed with data is pulled from one snapshot into another snapshot. The engine can merge multiple disks at the same time and each merge can independently fail or succeed in each operation. "
I think you have to mention that it is a restricted use case for now... and specify that it works only for Fedora 20 and in that case you have to manually modify the repo definition to install the qemu packages from virt-preview to get the feature.
This still is not fixed! I can already see the bugreports coming in, claiming live merge does not work, because the release notes are very misleading!

I'm more than available to change it if my edit rights allow it. But at the end I didn't see any clear answer from developers and/or infra maintainers... I think it is a crucial page, so I'd prefer one of them to do it or explicitly answering here that we are right and we can go change it... Gianluca
