[Users] Clome thin provision to thin provision??

Hello: Is it possible to clone a vm with thin provisioned disks to another vm with thin provisioned disks too? Currently when I clone a VM from a snapshot, although I choose "thin provision" in "resource allocation"->"Storage Allocation" from the "Clone VM from Snapshot dialog", the VM is created with preallocated disk(s) Is this the default or there is a problem with my engine/nodes installation? Engine: Centos 6.5, ovirt-engine 3.4.0-1.el6 Nodes: Centos 6.5, vdsm-4.13.3-2.el6
