Just to clarify this: 1. Version 3 of the SDK only works with version 3 of the API. 2. Version 4 of the SDK only works with version 4 of the API. 3. Version 3 of the engine only supports version 3 of the API. 4. Versions 4.0 and 4.1 of the engine support both version 3 and 4 of the API. This means that with version 4 of the engine you can use both versions of the SDK. This will change with version 4.2 of the engine. There we will remove support for version 3 of the API, so you will need to use version 4 of the SDK. _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
