The issue, as I perceive it, is newbies find Jason Brook's blog:
  http://community.redhat.com/blog/2014/11/up-and-running-with-ovirt-3-5-part-two/

And then newbies think this Red Hat blog is production quality.  In my
opinion, the blog how-to is okay (not really, IMHO) for a lab, but not for
production.

Since fencing is important in oVirt, having gluster on the hosts is a no-no
since a non-responsive host could be fenced at any time -- and the engine
could fence multiple hosts (and bork a locally hosted gluster file system and
then screw up the entire gluster cluster).
