There are some options for clone disk for other platform like oVirt.
--clonetype [thin|full]
A thin clone uses copy-on-write (COW) reflinked clone meaning it
is dependent on the base template, but enables rapid cloning.
Full clone will make a full physical copy hence not be dependent
on the base template.

I want to know which type is oVirt using when we clone vm from
template ?
We support both.
When creating a vm you can select to optimize for Server or Desktop.
- For Server we default to creating the vm image by cloning the
template to a new disk.
The vm does not depend on the template disk.
- For Sesktop we default to creating a thin disk using the template
disk as a backing file.
This vm depends on the template.
To select different storage allocation you can open the "Resource
Allocation" tab and
select Clone or Thin from the "Storage allocation" section.
See the attached screenshots.
