This is still an issue on 6.4.1 snap 2:

I can still see it in 6.4.2.1:

E Command "host create" finished with return_code 64
E stderr contains following message:
E [ERROR 2019-03-24T02:24:47 Exception] Error: Unrecognised option '--content-source-id'.

or:

E Command "host create" finished with return_code 64
E stderr contains following message:
E [ERROR 2019-03-24T02:26:34 Exception] Error: Unrecognised option '--content-view-id'.

I assume it is same issue.

The Satellite Team is attempting to provide an accurate backlog of bugzilla requests which we feel will be resolved in the next few releases. We do not believe this bugzilla will meet that criteria, and have plans to close it out in 1 month. This is not a reflection on the validity of the request, but a reflection of the many priorities for the product. If you have any concerns about this, feel free to contact Red Hat Technical Support or your account team. If we do not hear from you, we will close this bug out. Thank you.

Thank you for your interest in Satellite 6. We have evaluated this request, and while we recognize that it is a valid request, we do not expect this to be implemented in the product in the foreseeable future. This is due to other priorities for the product, and not a reflection on the request itself. We are therefore closing this out as WONTFIX. If you have any concerns about this, please do not reopen. Instead, feel free to contact Red Hat Technical Support. Thank you.
