Is this related to the NFS server which gluster provides, or is
because of the way gluster does replication?

There's a few posts ie.
http://community.redhat.com/blog/2014/05/ovirt-3-4-glusterized/ which
are reporting success with gluster + hosted engine. So it'd be good to
know, so we could possibly try a work around.

Cheers.
