i have these steps courtesy of haim ateya worth trying:
    * add new volume constructed from one brick
      - volume name = myVol
      - brick dir = /opt/myBrick
    * start volume
  - ssh to node
    * chown -R vdsm:kvm /opt/myBrick
  - using ovirt do the following):
    * create new DC (Posix compliant FS)
    * create new cluster
    * add new host (virt)
    * new domain dialog
      - path = node:/myVol
      - VFS Type = glusterfs
      - Mount Options = vers=3
    * if start vm failedt to selinux - disable SELINUX on host

you would need the newer kernel with direct_io iirc
