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

Nobody working on oVirt is testing any release of Openstack in the recent years.

The Cinder/Ceph support was released as tech preview in 3.6, and no work was

done since then, and I think this will be deprecated soon.

For 4.3 we are working on a different direction, using Cinderlib

https://github.com/Akrog/cinderlib

This is a way to use Cinder drivers without Openstack installation.

The same library is used to provide Cinder based storage in Kubernetes.

You can find an early draft here for this feature. Note that it is expected to be

updated in the next weeks, but it can give you some idea on what we are

working on.

https://github.com/oVirt/ovirt-site/blob/f88f38ebb9afff656ab68a2d60c2b3ae88c21860/source/develop/release-management/features/storage/cinderlib-integration.html.md

This will be tested with some version of Cinder drivers. I guess we will have

more info about it during 4.3 development.

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)

I think Glance support should work. Elad, which version of Glance was

tested for 4.2?

Regarding which Openstack version can work best with oVirt, maybe

Openstack guys I added can give a better answer.

Nir

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
