Description of problem: I encountered some feedback on #rhev from a user who was having difficulty finding a RHEV-H image for use with 3.1 Beta. Initially they tried with a 6.2 ISO and then a 6.3 ISO. but the one from the "real" RHEV-H channel. I'd like to add a release note to explain that only RHEV-H from rhel-x86_64-server-6-rhevh-beta will work with 3.1 clusters. We actually did mention this in the documentation itself (I just checked the install guide) but I think that customers who are already familiar with RHEV probably didn't notice and expected the RHEV-H 6.3 ISOs to always work (not knowing that we have a further update to it coming that will coincide with RHEV 3.1 GA).
Closing, we don't need this open for inclusion in the release notes.
