That blog was focused on Hosted Engine setup where one wanted to leverage
a pre-existing Ceph installation for storage (both for the dedicated
storage domain to assign to the hosted engine VM and for other storage
domains to be used for "regular" VMs).
Cinderlib was not supported for the initial hosted engine setup (where you
create the hosted engine dedicated storage domain) and the blog describes
how to overcome the limitation and configure your existing Ceph cluster
iSCSI gateway functionality, so that you make the initial install of oVirt
specifying iSCSi storage type
Then the blog describes how to use cinderlib for new storage domains after
install, to be used for "regular" VMs.

I don't know if there is a copy of the old 4.4 ones anywhere....
you have to use this one (command line based):
https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_...
and there the section 3.2 Preparing iSCSI Storage
https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_...
is managed by you using the blog info above for iSCSI Gateway, and
eventually further modifications due to possible new releases of Ceph...
I can't find any instructions about cinder/ceph in ovirt docs.

This is because it is not supported, neither in RHV nor in oVirt. I don't
know where you can find the cinderlib part for oVirt now.
But you can refer to this Red Hat solution
https://access.redhat.com/solutions/5605141
(possibly you need a subscription, perhaps the free developer one is
sufficient)
You have to adapt the repos part for oVirt/CentOS Stream, though
Sandro, any added information here for oVirt repos to configure cinderlib
on oVirt 4.5?
Repos enabled by default in oVirt 4.5 should already set up the right
configuration for getting Ceph Pacific and RDO Yoga Cinderlib.
It would be interesting for a 4.6 release a rebase on Quincy/Zed if someone
wants to take the challenge.
