[ovirt-users] Best Openstack version to integrate with oVirt 4.2.7

Hello, do you think it is ok to use Rocky version of Openstack to integrate its services with oVirt 4.2.7 on CentOS 7? I see on https://repos.fedorapeople.org/repos/openstack/ that, if Rocky is too new, between the older releases available there are, from newer to older: Queens Pike Ocata Newton At the moment I have two separate lab environments: oVirt with 4.2.7 Openstack with Rocky (single host with packstack allinone) just trying first integration steps with these versions, it seems I'm not able to communicate with glance, because I get in engine.log 2018-11-10 17:32:58,386+01 ERROR [org.ovirt.engine.core.bll.provider.storage.AbstractOpenStackStorageProviderProxy] (default task-51) [e2fccee7-1bb2-400f-b8d3-b87b679117d1] Not Found (OpenStack response error code: 404) Nothing in glance logs on openstack, apparently. In my test I'm using http://xxx.xxx.xxx.xxx:9292 as provider url checked the authentication check box and glance user with its password 35357 as the port and services as the tenant a telnet on port 9292 of openstack server from engine to openstack is ok similar with cinder I get: 2018-11-10 17:45:42,226+01 ERROR [org.ovirt.engine.core.bll.provider.storage.AbstractOpenStackStorageProviderProxy] (default task-50) [32a31aa7-fe3f-460c-a8b9-cc9b277deab7] Not Found (OpenStack response error code: 404) So before digging more I would lile to be certain which one is currently the best combination, possibly keeping as fixed the oVirt version to 4.2.7. Thanks, Gianluca
