Indeed. A felt like there was need for a simple way to backup ovirt vms.
Ansible may just be the answer. After some more testing of the playbook I
plan to publish a blog post/guide on the subject so others can use it.

Jayme is trying to solve pretty much the same problem as you - although
he's using the Ansible approach instead of SDK. Feel free to join that
