[ovirt-users] Automatic snapshot

Hi, I study the snapshot possibillities in ovirt. I would like to make a cron running every day which: - retrieve vm list from a specific cluster - create a new snapshot (without memory) for every vm - removes oldest snapshot to keep only 5. I'm wondering what is the best approach to do that? use a list of command in batch for "ovirt-shell", scripting a bit with python, using the api ovirt? Unless there is already something to find something. Thank you for helping -- Lionel
