You need to use version 3.6.0.0 of the SDK, or newer, as that is where
the support for this "use_cloud_init" parameter was added.

The new parameter is part of the "Action" class, so in your code you
need to set it:

  actionData.setUseCloudInit(true);

I take the opportunity to remind you that in version 4.2 of the engine
we will drop support for version 3 of the API and of version 3 of the
SDKs. So, once you migrate to version 4 of the engine consider using
version 4 of the SDK. There is an example of how to use cloud-init with
version 4 of the SDK here:


https://github.com/oVirt/ovirt-engine-sdk-java/blob/master/sdk/src/test/java/org/ovirt/engine/sdk4/examples/StartVmWithCloudInit.java

Note that this won't work with version 3.6 of the engine, for that you
need to keep using version 3 of the SDK.
