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

[Alessandro De Salvo]

Hi,

we're also extensively using ceph via cinder on docker (Kolla project), 
but we're stuck on Pike for the missing keystone v3 support.


While cinderlib is desirable and it's a good solution for simple uses, 
adding support for keystone v3 and keeping the native cinder interface 
would also be good, for cases where you already have an openstack 
infrastructure available and you want to manage a storage system from a 
single place. The other reason to keep the current solution, at least 
for now, is what Matthias is mentioning: the transition phases.


How difficult it is to add the keystone v3 support for the storage side 
in ovirt, given you should already have the needed libs as you use them 
for the networking?


Thanks,


   Alessandro

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.
https://github.com/Akrog/ember-csi

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.

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)

for a packstack network host it is just:
systemctl stop iptables
yum install -y https://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm
before adding the host in oVirt

I see that when configuring "OpenStack Image" provider the authentication
section contain "API Version" field greyed and pre-filled with "v2.0", so I
cannot change it
When trying to configure Openstack Neutron provider I can select "v2.0" or
"v3"

I don't find clear reference on how to manually configure the network node
as a host.
Is it sufficient to enable ovirt 4.2 repos and install
vdsm-hook-openstacknet on it and then add it to the manager?

Right, when I wrote "Openstack" I meant "Cinder/Ceph".

Strange... I think oVirt is the natural platform to test features to have
them on RHV if considered enterprise ready.
And reading the downstream latest documentation for RHV 4.2 I see this
regarding external providers:
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/html/administration_guide/chap-external_providers

And there is explicit reference to

1) Glance
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/html/administration_guide/sect-adding_external_providers#Adding_an_OpenStack_Image_Service_Glance_for_Image_Management

"

Red Hat Virtualization supports Red Hat OpenStack Platform versions 8, 9,

"

BTW: the release cycles are here:

3) Cinder

with Cinder
"
Add an OpenStack Block Storage (Cinder) instance for storage management to
the Red Hat Virtualization Manager. The OpenStack Cinder volumes are
provisioned by Ceph Storage.
"

Coming back to oVirt 4.2.7 I see all of the 3 above providers present and
referenced when I go and add external providers, so it doesn't seem to the
final user/admin as an abandoned feature

Based on the restrictions described for Neutron Provider above, I right
deployed, always on CentOS 7.5 and using packstack allinone method, the
oldest release I found a repo for at
http://mirror.centos.org/centos/7/cloud/x86_64/ .
That is Ocata (aka the base for OSP 11) and at least the glance connection
works now out of the box, using the same parameters that dind't work with
Rocky.

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.
https://github.com/Akrog/ember-csi

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.

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.
