[libvirt] Problen in cloning of thin LVM

Hi all, I have create a Thin lvm and installed a guest os on it, Now when i cloned that lvm using virt-clone # virt-clone --prompt --force --original lvm_thin1 --name lvm_thin2 --file /dev/volgrp/lvm_thin2 The cloned Disk lvm_thin2 size is fully expanded , But I want a thin Lvm cloned image Well according to my best of knowledge , It could be because the when lvm is getting cloned, The zero are read from the original image #lvs LV VG Attr LSize Pool Origin Data% lvm_thin1 Volgrp Vwi-aotz 8.00g pool 12.18 lvm_thin2 volgrp Vwi-a-tz 8.00g pool 100.00 pool volgrp twi-a-tz 100.00g 8.97 As you can see above the original LVM utilize only 12.18% disk space from the pool, but the cloned lvm_thin2 is fully expanded. Is there is any way how can I clone a THIN LVM without fully expanding it ? Or Is there any way to shrink the cloned LVM to that size without loss of data.
