oVirt 3.2 needs a newer (3.4.0) version of glusterfs, which is
currently in alpha and hence not available in stable repositories.
http://bits.gluster.org/pub/gluster/glusterfs/3.4.0alpha/
Shireesh, this should be specifed in vdsm.spec - please patch both
master and ovirt-3.2 branches.
Beyond that, there's a problem of Python 2.6 missing ParseError.
This issue has been reported multiple times now, and I think it
needs an update to the oVirt 3.2 release notes. Have added a note to
this effect at:
