AHAH Dereck, thx for googling,
I knew I could google it, that's not an expert stuff, nevertheless as you seemed to
be aware of the SDK subject I was wondering if you have links you find yourself useful
(even from google), so that I can dive into them.
I'll partially repeat what I wrote before, but include links, just to make sure:
I highly encourage you (and everyone) to have a look at:
https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk/examples
https://github.com/oVirt/ovirt-ansible/tree/master/examples
Thx.

That's not the point. I was not part of the decision to drop ovirt-shell, but
think it made sense. If you need to do complex stuff with it, you practically
spend time on learning a new language, which is oVirt-specific, and so won't
be useful for you for anything else you might do in the future. If you instead
spend time on learning either python or ansible, you learn languages that are
useful for other things you might want to automate. I think both of them suite
very well the "sysadmin sometimes playing a developer" role.
(I played that role myself for ~ 15 years, before joining Red Hat as a "real"
developer, so speak from experience...)
If you miss ovirt-shell itself (I guess mainly because for very simple things
you could do stuff in a single command-line, and that's probably uglier to do
with either ansible or python (although doable)), the below project was already
mentioned in this thread elsewhere. I never tried it myself:
