I want to create a cloned virtual machine based on a template with SDK API python and i don't find the parameter to indicate the clone action for the disk<br>

If the data_domain_name is the same as the template data domain, then this script seem to create a vm but not with cloned disk.<br>
<br>
If the data_domain_name is NOT the same as the template data domain, then this script produce an error<br>
ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Cannot add VM. The selected Storage Domain does not contain the VM Template.]". HTTP response code is 400.<br>
<br>
So how to create a cloned virtual machine based on a template ?<br>
<br>
I think i'm looking for the same parameter on the web ui, "Storage Allocation" => Thin/Clone<br>
