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
