i still do not understand why you'd want this?
as you already tried, you can clone it across nodes already, why would
you need the templates on all nodes?

hmm? what exactly did you do and why do you think that they are
full clones?

i just tested it here and converting a 'linked clone' to template
simply renames the vm disks to 'base-...'

'rbd ls -l'

still shows me the correct parent image...
