[libvirt PATCH] conf: Add support for GlusterFS volumes as disk
While libvirt has support for GlusterFS pools and volumes, they cannot
be added to a domain. This commit adds the necessary translation between
the pool definition and the disk definition, allowing volumes in a domain
to be backed by a gluster pool.
