Please see my reply from a few minutes ago to the thread
"[ovirt-users] ovirt-imageio : can't upload / download".
engine-setup sets up an engine, after it's installed, inside some machine.
ovirt-hosted-engine-setup (or the cockpit UI) sets up a hosted-engine.
It creates a VM and sets up the engine inside it (also using
engine-setup in the process, non-interactively).

There is also "HCI", which cockpit also allows you to setup - storage
is gluster, setup on the same host(s).

If you do this mainly for learning, then I suggest that you first play
with a standalone engine. Install and setup an engine somewhere (can
be a physical machine or a VM managed e.g. by virt-manager), Add a
host (can be another VM, using nested-kvm), add storage (can be nfs or
iscsi on another VM), create VMs etc., get a feeling for it. Then, try
hosted-engine - using CLI or cockpit - can also be in a VM (again,
nested-kvm).
If it's for production, or in preparation for production, and you do
not have time to play with all the options, spend some time reading
and designing what you intend to do, then do this first on a test
setup (made of VMs) and then on the actual production machines.

This does setup also storage.
If you meant to say that CLI does not allow setting HCI, then, sadly,
I do not know this well, never tried it myself :-(, but in principle
should be doable - search for "gdeploy".

If still not clear/solved, please provide more details - the exact
question, your answer, relevant snippet from the logs.
You can of course replace real names with some placeholders if you do
not want to reveal them.
Good luck and best regards,
