do a 'virsh -r dumpxml yourvm' and have a look at the output should like
like:

    <disk type='network' device='disk' snapshot='no'>
      <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/>
      <source protocol='gluster' name='GlusterSSD/e11866bf-1120-4c87-a992-9be32f110b8d/images/09ca5046-ab7a-11d8-9f2a-ffac3e89a6ad/042a9f7d-15be-443d-bcf7-a2ba8db43f72'>
        <host name='test.com' port='0'/>
      </source>
      <target dev='vda' bus='virtio'/>
      <serial>09ca5046-ab7a-4bd8-9f2a-ffac3e89a6ad</serial>
      <boot order='1'/>
      <alias name='virtio-disk0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
    </disk>

The first line is import type=network indicates that its using libgfapi.
