Description of problem:
Currently gluster volumes have to be mounted and images are created/accessed over the mount. With the introduction of GlusterFS libgfapi, QEMU supports glusterfs through libgfapi directly. This we call as QEMU driver for glusterfs.
A build of VDSM with this support was created in:
http://jenkins.ovirt.org/job/vdsm_libgfapi_master_create_rpms_nightly/search/?q=vdsm_master-libgfapi_create-rpms
We need to test this functionality.
