1) Environment with All-In-One F20
installing oVirt AIO on F20 automatically gives the virt-preview repo through the ovirt-3.5-dependencies.repo file, but only for libvirt* packages:
the same server is the engine and the hypervisor
[root@tekkaman qemu]# rpm -q libvirt libvirt-1.2.9.1-1.fc20.x86_64
[root@tekkaman qemu]# vdsClient -s 0 getVdsCaps | grep -i merge liveMerge = 'true'
but [root@tekkaman qemu]# rpm -q qemu qemu-1.6.2-10.fc20.x86_64
So that tryng live merge it initially start but you get this in vdsm.log: libvirtError: unsupported configuration: active commit not supported with this QEMU binary
2) Another seaparate environment with a dedicated 3.5 engine f20 engine and 4 test cases tried
a) ovirt node installed and put in a dedicated cluster latest available seems ovirt-node-iso-3.5.0.ovirt35.20140912.el6.iso from 3.5 rc test days

was this resolved?
In my opinion it was not resolved and what written into release notes doesn't correspond to features set. See my test cases and eventually describe other test cases where live merge is usable See also other findings about live merge on active layer here: http://lists.ovirt.org/pipermail/users/2014-November/029450.html Gianluca
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. ----- Original Message -----

This is expected behavior. You also need to install the qemu packages from virt-preview to get the feature.

Live merge is not supported on EL6, period. It was simply not possible to backport all of the features into those versions of qemu and libvirt.
b) f20 + latest updates host installed as OS and then installed from webadmin in another cluster virt-preview on host it is not enabled so that libvirt/qemu are not ready

Great, this is working as expected.
c) CentOS 6.6 host + latest updates installed as OS and then installed from webadmin in another cluster

Also expected due to specific lack of support for el6.
d) CentOS 7.0 host + latest updates installed as OS and then installed from webadmin in another cluster

Understand me, please. My note was about Release Notes page misleading in respect with features' set. At 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.

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

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
