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 need to setup cinderlib but the referenced link is dead: > https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_... The web interface has been desupported in 4.5, so you cannot find it anymore in official 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?
