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.
