Hi, I am also completely frustrated by this. In my opinion, templates should allow us to do simple "mass instantiation" even with persistent disks: create VM => save it as a template => instantiate i.e. 10 new VMs at once, each with its own copy of template-based persistent disk
Another highly appreciated feature of templates would be the "linked" state: to propagate future changes in the template to the VMs instantiated from it, at least for some attributes. Is there any chance some of those features get implemented in the near future ? Or has it already been done and I am just missing the whole concept by misunderstandning the documentation ? If so, is there any direct URL to a step-by-step guide, how to achieve this ?
