Ok, as I thought. But how does others handle that, like moVirt e.g? Is there
a best-practice for backwards compatibility?
Right now if you use the old SDK you should be able to "talk" with both 3.6 and
4.0, because 4.0 api provides backward compatibility with 3.6. But I'm not sure if you
can rely on this. Juan may have more details for you.
Thanks,
Rafael

moVirt is not using the SDKs, it is talking to API directly. But the general rule for the
clients
(moVirt but also ManageIQ) works like this:
- check the version of the API right at the beginning
- according to the found version use either the new or the old api
Right now if you use the old SDK you should be able to "talk" with both 3.6
and 4.0, because 4.0 api provides backward compatibility with 3.6. But I'm
not sure if you can rely on this. Juan may have more details for you.

Ah, I see. OK, that answers my question pretty clearly, correct me if
I'm wrong; for anyone who wishes to write something in python, you
have two SDK's installed (or, talk to the API directly) and check the
API version to determine which SDK you should use?
Is there a standard ("correct") way of checking the API version?

Right now if you use the old SDK you should be able to "talk" with both 3.6 and
4.0, because 4.0 api provides backward compatibility with 3.6. But I'm not sure if you
can rely on this. Juan may have more details for you.
It is important to understand the following:
* There are two different versions of the API: version 3 and version 4.
* Version 3 of the engine implements only version 3 of the API.
* Version 4 of the engine implements versions 3 and 4 of the API. This
is the current situation. In version 4.2 we will probably drop suport
for version 3 of the API completely.
* Version 3 of the SDK implements only version 3 of the SDK. The name of
the package is "ovirt-engine-sdk-python".
* Version 4 of the SDK implements only version 4 of the SDK. The name of
the package is "python-ovirt-engine-sdk4".
In your specific use case, version 4.0.3 of the
"python-ovirt-engine-sdk4" package can't talk to version 3.6.X of the
engine. But as Rafael says, you can install version 3 of the SDK, the
"ovirt-engine-sdk-python" package, and then it will version 3.6.X of the
engine.
