[ovirt-users] How to use sysprep to create Windows templates

Hi, I need to create some Windows Templates for my client, and I am not quite familiar with the Windows sysprep installations. I read the "Sealing a Windows Virtual Machine for Deployment as a Template" on the Virtual Machine Management Guide. What I don't understand is the process of sealing a Windows VM. When should I use the /usr/share/ovirt-engine/conf/sysprep/sysprep.* files? at the creation of the VM that will be a template at the end? or at the creation of new VMs based on the template? When should I use the /etc/ovirt-engine/osinfo.conf.d/xx.files.properties? at the creation of the VM that will be a template at the end? or at the creation of new VMs based on the template? What is the difference between : "Use Cloud-Init/Sysprep" in the VM edit window and the RUN Once window? For me it is not clear, could someone help me to understand. Regards.
