Hi all, I'm planning to migrate my ovirt el6 hosts to el7. Excepting that el6 will not be supported in next release of ovirt, is there a difference of performance between el7 and el6? I mean, are qemu or libvirt for example at the same level of performance/capabilities in el6 than in el7 (knowing that qemu-kvm 0.12 is still backported on el6) ? I heard that el7.1 will support live merge, if true will el6.7 support it as well or the difference between them is there?
http://lists.ovirt.org/pipermail/users/2014-September/027421.html Downstream RHEV must support el6, so Itamar suggests to exclude el6 in 3.6 cluster level, but el6 will be supported in 3.5 cluster. It may mean that el6 hosts won't beneficiate of latest 3.6 features... Le 19/02/2015 10:30, Nicolas Ecarnot a écrit :

I don't think it's related to RHEV, but new oVirt 3.6 features would not be supported on el6 hosts. clusterLevel 3.6 depends on libvirt/qemu features that are not expected to backported. It's time to move on.

OK. Thank you Nathanaël and Dan.
It's time to move on.

I'm not aware of plans to backport live merge to el6.7 el7.x is expected to have much newer versions of qemu/libvirt than .el6.
