Easy UTM Cloning of VMs.

Consider you have set up template VMs in UTM, you can easily clone them using this script which takes care of MAC randomization, and configuring the ~/.ssh/config file so you can immediately connect. The script is not bullet proof by any standards, and is somewhat opinionated. See my blog post on Template setups and usage.
