When I try adding an EL 6.3 based node to an ovirt 3.1 cluster, ovirt

With ovirt 3.1 EL 6.3 nodes will only work with a data center set to 3.0 compatibility mode. Is there any reason(s) why EL 6.3+ nodes would not be allowed in a 3.1 compatibility level cluster?<br>

Why would they only work in 3.0 compatibility? 3.1 nodes work in 3.1 cluster level because, well, they are the same version.<br>
Or I didn&#39;t get the question and please elaborate:)<br>

This assumes non use of gluster since adding vdsm-gluster to an EL 6 node requires some work package update/version wise (not impossible).<br>
