Hi Gianluca,
thank you for the feedback with the templates.
I will take a look into it.
Best regards

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:

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?
