Hi Joop,
what version of oVirt? The bug says solved in 3.5beta1, because that uses
gluster 3.5.1 packages from here:
http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-6/x86_64/

There were bugs opened for both libvirt and glusterfs so that they could
manage better ephemeral ports allocation if already taken by others.
They are all solved upstream, but not in CentOS 6.5 mainstream neither for
libvirt (centOS) nor for gluster (epel) afaik.

As it is solved in glusterfs in 3.4.2qa4 upstream, you could try changing
config file for gluster volumes as explained in this bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=987555
after you upgrade your gluster packages

You can also download packages using similar repo for 3.4.3/3.4.4
http://download.gluster.org/pub/gluster/glusterfs/3.4/3.4.3/EPEL.repo/
or
http://download.gluster.org/pub/gluster/glusterfs/3.4/3.4.4/EPEL.repo/
I successfully tried some months ago on F19 when there was similar problem.
I don't know if it would be any package conflict with current version of
CentOS and/or ovirt 3.4 packages if you use them
