Actually there are SDKs for other languages: https://gerrit.ovirt.org/#/admin/projects/?filter=sdk https://github.com/oVirt?q=sdk== JS is empty, but the others are more-or-less alive. Python is indeed the most "invested", at least in terms of number of example scripts, but IIUC all of them are generated, so should be complete.

Thank you for your input. Turns out it's probably not an issue right now anyways because my understanding is that there is no "live" upgrade path from 4.3/7.x to 4.4/8.x. My understanding is that the only upgrade path is a re-install. If that's the case, then I suspect it will be a VERY long time until I upgrade, because I'm on a single-host production system so can't stage a reinstall the same way I can stage a "yum upgrade". > Also, Ansible is declarative , while python will need more effort. I guess only time will tell ;) There wasn't a significant learning curve to python (as I've already had experience with it, and most of what I needed to do was already in the SDK examples). Ansible is a tool I have never even looked at, let alone tried to use it, so I suspect it would take me more than a couple hours to get it working. > Best Regards, > Strahil Nikolov -derek -- Derek Atkins 617-623-3745 de...@ihtfp.com www.ihtfp.com Computer and Internet Security Consultant ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/Y5ZOZHNN4ERKPAGZ3QN5D7RY3ZC4XQPG/

Hi Derek, I also don't like Python (and I prefer Salt instead of Ansible), but Ansible is the wiser option /personal opinion/ . My reasons - API change , so your code will eventually will die. With Ansible - a lot of people use it and there is a high chance that some updates the Ansible module that will do the job even after the API changes. Also, Ansible is declarative , while python will need more effort.
