[Users] oVirt 3.2 on CentOS with Gluster 3.3

[Rob Zwissler]

Running CentOS 6.3 with the following VDSM packages from dre's repo:

vdsm-xmlrpc-4.10.3-0.30.19.el6.noarch
vdsm-gluster-4.10.3-0.30.19.el6.noarch
vdsm-python-4.10.3-0.30.19.el6.x86_64
vdsm-4.10.3-0.30.19.el6.x86_64
vdsm-cli-4.10.3-0.30.19.el6.noarch

And the following gluster packages from the gluster repo:

glusterfs-3.3.1-1.el6.x86_64
glusterfs-fuse-3.3.1-1.el6.x86_64
glusterfs-vim-3.2.7-1.el6.x86_64
glusterfs-server-3.3.1-1.el6.x86_64

I get the following errors in vdsm.log:

And, long story short, the gluster integration with oVirt does not
work.  As per Vijay Bellur's comments at
http://list-archives.org/2012/12/27/users-ovirt-org/continuing-my-ovirt-3-2-nightlies-queste/f/7132789998
this is due to a difference in the XML formatting output by gluster
vs. what is expected by VDSM, and is fixed in Gluster 3.4, which is
currently in alpha pre-release.

So my question is, was oVirt v3.2 released with a dependency on a
version of Gluster that is in alpha, or is there another workaround or
fix for this?
