I followed your instructions (and similar suggestions by others). I was
installing the host only, so commented out everything in my file except
install EPEL and ovirt repos. I'm not interested in hearing about what
"should" happen, or what happened on 6.4. These are the (unfixed) problems
with 6.5, and they are real.
INSTALL FAILED with message:

The real truth is that there are three repos trying to serve up gluster
3.4.0 packages.

I had found a suggestion on the web to upgrade to 3.4.1, since the 3.4.0
versions can't figure out "who's on first".
So I went back and uncommented the glusterfs repo install. That changes
yum's perspective to:
# yum list gluster*

glusterfs-server.x86_64 3.4.1-3.el6 glusterfs-epel
Only by replacing the glusterfs-epel repo file that ovirt uses with a
different one, does version 3.4.1 become available, and the error goes away.
I got a message saying "Host office4a installation in progress. Cannot set
tuned profile." but that message did not stop the installation from
completing, but gives me enough reason to put back the line copying the
"tuned" profile, so ovirt finds what it is looking for.
The other problems did not appear this time, very possibly because of the
order in which I tackled things, based on the advice I got.
That leaves my install script looking like this (with all the 'if' statements
take out):
#!/bin/bash
# script to prepare Centos 6.5 minimal for ovirt host install process
# by Ted Miller
# 2013-12-16 tested on office4a
yum -y install yum-presto
yum -y upgrade
yum -y install wget
wget http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/glusterfs-epel.repo
yum -y install http://ovirt.org/releases/ovirt-release-el.noarch.rpm
yum -y install http://mirror.us.leaseweb.net/epel/6/i386/epel-release-6-8.noarch.rpm
cp -r /etc/tune-profiles/virtual-host /etc/tune-profiles/rhs-virtualization
That is significantly reduced from what I had, but still a long ways from the
"just install the epel and ovirt repos" that I was getting.
The version conflict that forced the addition of the glusterfs repo is
probably due to new versions of gluster in Centos 6.5.
The problem with "tune" was trying to fix a problem for RHES users, but
created a problem for everyone else (CentOS & etc).
