How do I create a copy-on-write qcow2 image based on another image file

Solution Unverified - Updated -


  • Using the 'clone' feature simply makes a copy of an image file on disk.

  • Copies are wasteful when only a small portion of the image will be changed from a template.

  • Snapshot support is needed along with capability to rebase from a set of changes.
