In general you can use a newer version of the SDKs and CLI with an older
engine, as the RESTAPI is backwards compatible. However, some options of
the newer SDKs and CLI won't work, as the support in the engine side
won't exist.

In this particular case you probably have an old version of the Python
SDK (the CLI sits on top of the Python SDK). To have the cloud-init
support you need at least version 3.3.3.0 of the ovirt-engine-sdk-python
package (better to use the latest, 3.3.3.1).

In addition, as I mentioned before, there is a bug around the "hostname"
attribute, it should have been "host-address". Auto-completion will tell
you that the option is --vm-initialization-cloud_init-hostname, but
actually it should be --vm-initialization-cloud_init-host-address.
Typing that manually should work. I opened the following bug to track
this issue:
