Neutron
by Zeeshan Haider 15 Sep '21

15 Sep '21

**Scenario**: We are trying to develop our Virtual Network using `Open Virtual Network` or `OVN`, We need our Virtual Network Switches running firstly on the root Virtual Router, and there are some other Virtual Switches as well. I was Working on the `openvswitch` and `OVN` but a lot of things are missing for me, and there are some unlinked dots between the deployment itself and there are some problems. My Question has 3 further Parts. 1. Is it possible at all to use `Neutron` as our Network Manager without OpenStack cloud installation? 2. Is it a good approach? 3. if not then are there any cookbooks available for `OVN`, I am not talking about man-pages. Any help would be highly appreciated. P.S. I am thinking about this because OVN got merged with Neutron, and it could be one of the possibilities. **Note**: Please Don't downvote the question because I don't have that much experience with the network could be a stupid question, will remove it if you provide me the info in the comment section. I have found out that installation is possible I am quoting the answer from `https://bugs.launchpad.net/neutron` by `https://launchpad.net/~amotoki` below. "The way to install neutron is simple: to install neutron with pip (from PyPI package or the git repo), prepare a config file for neutron and start the neutron server (in case of OVN mechanism driver). Distro packages and/or various tools like Ansible playbook are just a wrapper for this. The minimum required config to enable noauth (ie without keystone) is to set auth_strategy to noauth in the config file. I don't know the detail instruction step by step to satisfy your need." Now I want to find out detailed instructions for this purpose. is this possible to get the instructions here

[horizon] Support for Django 3.x
by Thomas Goirand 15 Sep '21

15 Sep '21

Hi, It's been a long time that Django 3.x is around, and therefore, it'd be nice if Horizon had some kind of support for it. Indeed, sooner or later, Django 3.x will be uploaded to Debian unstable. That day, I hope Horizon doesn't just break. So, what's the status? Is anyone is at least working on it? Cheers, Thomas Goirand (zigo)

[TripleO][RDO] Plan for TripleO packages in RDO Xena release
by Alfredo Moralejo Alonso 15 Sep '21

15 Sep '21

Hi, With OpenStack Xena GA approaching and TripleO as an independent project, we need to clarify how we will handle it in RDO Xena Release. According to the spec [1]: "TripleO would no longer be able to deploy all versions of OpenStack. One idea that was brough forth in the discussions around this topic thus far, is that we can attempt to address this by designating a range of git tags as compatible with a particular OpenStack stable branch." In practical terms: - When will this list be provided? Can I assume shortly after Xena release (around mid october)? - How will this "list of tags compatible with Xena" be provided by the TripleO project? - How may we describe the maintenance status of TripleO in RDO Xena release? We'd like to include a statement in the release notes. Best regards, Alfredo https://specs.openstack.org/openstack/tripleo-specs/specs/xena/tripleo-inde…

Need some clarification about tenant network in TripleO
by wodel youchi 15 Sep '21

15 Sep '21

Hi, It is a newbie question, but I didn't find a real answer, and I have trouble with my deployment, so some help will be appreciated. In the deployment of TripleO in network isolation, a Tenant network is created, that network (in the examples I have seen) have a VLAN-ID and a subnet. I did the same in my deployment, I created that network. My questions : - Is the Tenant network, mentioned in the deployment process, is it the first tenant network created for the admin tenant? and for new tenant I have to create a new network tenant, despite I am not seeing how I would do that? - Or is it a pipe (a conduit) used to pass the traffic of all the tenants that will be created after? Regards.
