  mode      => 'bridge',
  interface => 'br0',
}
::libvirt::network {'management':
  mode      => 'bridge',
  interface => 'br0',
}

::libvirt::network {'wan':
  mode      => 'bridge',
  interface =>'br2',
}

::libvirt::pool {'rbd-pool':
  type  => 'rbd',
  hosts => [ 
    'clservice1',
    'clservice2',
    'clservice3',
  ],
  auth => {
    'type'     => 'ceph',
    'username' =>' libvirt',
    'uuid'     => '07f089e4-fb59-4eb4-9b27-3030115006a0',
  },
}

::libvirt::secret {'client.libvirt':
  type  => 'ceph',
  uuid  => '07f089e4-fb59-4eb4-9b27-3030115006a0',
