[Users] Templates and originating VM relationship

Hello, oVirt 3.2.1 on Fedora 18. I customize a CentOS 6.4 VM and when I comfortable I select "make template". I don't take any snapshot for the VM before this. I thought that VM would have been disappeared, transforming itself into a template, instead at the end I have both the template and the originating VM. Apparently with the same name for the disk and the same storage domain.... What is exactly the relationship between them? Can I safely remove the originating VM? I already tested making template and then deleting it and then being able to power on again VM and make a new template from the originating VM. The rhevm 3.1 admin manual is not so clear about this: it contains a note regarding " Take a snapshot of the virtual machine at this stage if you wish to use the virtual machine (as a virtual machine) after using it to create a template. " But if behavior of oVirt 3.2.1 has to be the same with it, this doesn't explain itself based on my experience.... Thanks in advance for any information Gianluca
