At https://www.ovirt.org/develop/release-management/features/storage/cinderlib-... ist described the cinderlib integration into oVirt: Installation: - install centos-release-openstack-pike on engine and all hosts - install openstack-cinder and python-pip on engine - pip install cinderlib on engine - install python2-os-brick on all hosts - install ceph-common on engine and on all hosts Which software versions do you use on CentOS 7 whith oVirt 4.3.10? The package centos-release-openstack-pike, as described at the above-mentioned Managed Block Storage feature page, doesn't exist anymore in the CentOS repositories, so I have to switch to centos-release-openstack-queens or newer (rocky, stein, train). So I get (for using with ceph luminous 12): - openstack-cinder 12.0.10 - cinderlib 1.0.1 - ceph-common 12.2.11 - python2-os-brick 2.3.9
