Hi. What I want to ask is simple. System resource changes in the Pool VM do not seem to be supported by ovirt. So let me ask you two questions. 1. Can you tell what the reason is? Are you related to the ovf file? 2. Is there any other way to use sub-templates? (Manual work is also fine)  Is it possible to modify DB value only? If not, what else should I touch? Waiting for experts to answer. Thank you.
