Thanks Arik,
I am interested in the Thin approach.
Is it not possible to create it on another storage domain ? Even with API ?
I read here
http://ovirt.github.io/ovirt-engine-api-model/4.4/#services/vms
*When creating a virtual machine from a template or from a snapshot it is
usually useful to explicitly indicate in what storage domain to create the
disks for the virtual machine. If the virtual machine is created from a
template then this is achieved passing a set of disk_attachment elements
that indicate the mapping:*
Thanks,
Shantur

Assuming you're asking about the administration portal, it depends on the
selected allocation policy (which you can find in the Resource Allocation
tab of the add-VM dialog):
- If it is set to 'Clone' then you can select any other storage domain
that is available in the DC to clone the template's disk to
- If it is set to 'Thin' then a VM disk must reside on a storage domain
that contains the template's disk it is based on. You can copy the
template's disk(s) to another storage domain if you want a VM disk to be
created there
