Thank you very much! However, if you use virt-Sysprep, you need to use this tool to complete template creation inside the VM to be created. Using oVirt's own template encapsulation option, however, does not require you to log in to the VM to run similar commands. It's just that using the Virt-Sysprep tool gives you more autonomy and options to choose from, whereas oVirt's own template encapsulation options are fixed and you can't personalize more options. Am I getting that right?

Can I just ask again, I've seen this option when you're referring to sealed Linux, but I don't understand what it means? What is a sealed Linux, and how is it different from a non-sealed Linux?
