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. -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.
