Hi Gianluca,
I tried to clone the VM but it does not help. It is still thin allocation.
Best regards Christoph
Hi, I referred to this information for the clone of VM scenario: http://lists.ovirt.org/pipermail/users/2016-May/040129.html <http://lists.ovirt.org/pipermail/users/2016-May/040129.html> that contains:
" >What happens if you clone a source VM which is using "thin" ? The VM cloned from a thin templated base VM will be created with a full copy of the disk (as in "Clone" when creating from template) " but I have not tried myself recently with 4.0/4.1 versions
Instead I did test some days ago with 4.0.6 this scenario below as I wanted to convert a source thin provisioned VM to a preallocated template: VM is powered on create a snapshot of the VM select the snapshot line and select clone in resource allocation section of the new vm screen change allocation policy for the desired disk/s from thin provision to preallocated Then you can decommission old VM and use the cloned one Verified today in 4.1 too.
Or from the snapshot line you can also "make template" if you plan to use it as a base for more VMs. But in this case (tested in 4.1) your options are shown in a "Format" column, not "Allocation Policy" column; and you can choose between QCOW2 (that should be thin) and Raw (that should be preallocated). See my screenshot: https://drive.google.com/file/d/0BwoPbcrMv8mvTHIzTU5kdHVJOG8/view?usp=sharin... <https://drive.google.com/file/d/0BwoPbcrMv8mvTHIzTU5kdHVJOG8/view?usp=sharing> Probably it should be made consistent and show "Allocation Policy" instead and related values?

Hi, I just tested this on 4.1: - take a VM with a thin provisioned disk How to see allocation policy? It seems suboptimal for me: I would expect to see this kind of information in disks sub pane of the vm. Instead I have to select snaphsots sub pane, then for example the "Current' line, and at the right side sub pane in disks tab I see "Allocation Policy" - thin provision
- make a clone of it in a new VM In the same sub pane for the new VM I see preallocated.... so it seems to work as I read This is on FC-SAN. What kind of storage is yours?
