Seems like different libvirt versions generate a storage volume name in different format. We would like to learn how libvirt names a storage volume under a block based storage pool. So that we may properly extract the LUN identifier out of the volume name for now and in the future.

On host A loaded with libvirt 0.8.7
# virsh vol-list SanPool1
Name Path
-----------------------------------------
unit:0:0:11 /dev/disk/by-id/wwn-0x600a0b800013071a000035ec4e32b832

On host B loaded with libvirt 0.8.1

# virsh vol-list SanPool1
Name Path
-----------------------------------------
1.0.0.0 /dev/disk/by-id/wwn-0x60080e500017e1d40000d0b74d873b13
