I'm far from being a programmer, but as I went to compare build
environments, between
qemu-kvm-rhev-0.12.1.2-2.415.el6_5.3.src.rpm
and
qemu-kvm-0.12.1.2-2.415.el6_5.3.src.rpm
in related spec file I see

rhel-6.5
and apart other probably not trivial implications, such as guest agent
part, I see that the "configure" command takes one extra argument in
base RH EL 6.5, that is
--disable-rhev-features
The only patch file containing this keyword is
kvm-Block-streaming-disable-for-RHEL.patch
and inside it there are these lines that impacts configure options and
related built qemu-kvm:

I don't think the rhev argument has instead implications in upstream
source qemu-kvm-0.12.1.2.tar.gz
So I think that if you want to dig more and if you have more
competences, you have to see the full spec file and the full patch
above.
Files downloaded here:
upstream
http://ftp.redhat.com/redhat/linux/enterprise/6Server/en/os/SRPMS/qemu-kvm-0.12.1.2-2.415.el6_5.3.src.rpm
rhev
http://ftp.redhat.com/redhat/linux/enterprise/6Server/en/RHEV/SRPMS/qemu-kvm-rhev-0.12.1.2-2.415.el6_5.3.src.rpm
Just for the record, we have setup a jenkins job to rebuild qemu-kvm for
el6 until we get it officially from centos:

I think this calls for an oldschool question/statement;
Who da man? ... You da man! :)
Live snapshot now just works. Haven´t verified quiesce yet though, but
looks good as far as the events in webadmin is concerned. Next to test
is live disk migration.
Thanks a lot for the feedback :)

Hey,
have gone through the logs to verify quiescence and the only thing
actually mentioning it comes from vdsm.log:
Thread-127371::DEBUG::2014-02-19
14:54:15,612::BindingXMLRPC::977::vds::(wrapper) return vmSnapshot with
{'status': {'message': 'Done', 'code': 0}, 'quiesce': False}
What is it saying really? That quiescing failed, or that it was
deliberately taken without it, or what?
Nothing in qemu-ga.log either, even if changed to "--verbose". Like it
never got any calls to quiesce in the first place. The guest does have
the device[1] attached at least. The guest is CentOS-6.4 or 5, if that
matters.
[1]: /dev/virtio-ports/org.qemu.guest_agent.0
libvirt log?
