Have you taken care of setting the required glusterd and volume options?  
these are described here:
- http://www.gluster.org/community/documentation/index.php/Libgfapi_with_qemu_libvirt

After setting the server.allow-insecure volume option, a stop and 
a start of the volume is needed (in 3.5).

HTH,
Niels
