[ovirt-users] el6 vs el7

[Nathanaël Blanchet]

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?
