It's centos 6.5. Have I need to change my repo ? I have just EPEL and Ovirt repo.
Unfortunately we don't have any repo for this yet, only the packages recompiled with such feature enabled available to download in the url that I have provided. We are working with CentOS guys to have an official repo for it.

Yes it's a live snapshots. Normal snapshot works.
Question: Is it a EL6 hosts? If yes, are you using qemu-kvm from: jenkins.ovirt.org/view/__Packaging/job/qemu-kvm-rhev___create_rpms_el6/ <http://jenkins.ovirt.org/view/Packaging/job/qemu-kvm-rhev_create_rpms_el6/> ?
Thanks!
