Tomas, thank you for your input. I am creating the template from a new Ubuntu VM that I have created. I have noted that generally my centos/rocky VMs can be created from VMs without issue. It has only been Ubuntu that is giving me grief. That being said, I only have one Ubuntu VM in my environment that needs to be made into a template. Fix the template or recreate it makes no difference to me. As long as the template is usable that's all that matters. I have block storage, not NFS. You mention needing to prepare the disk images first... how? In my experience I didn't need to do that for any centos VMs. I just clicked make template in GUI, selected QCOW image type and seal VM option. In a few minutes everything was done and I could use the new template.
