No network-segment-range support

[Nobuto Murata]

At this point, Charmed OpenStack deployment doesn't have Network segment ranges support.

$ openstack extension list --network
-> doesn't return "network-segment-range"

From the upstream documentation, there is a limitation in terms of operations if we miss the service plugin.

https://docs.openstack.org/neutron/latest/admin/config-network-segment-ranges.html
> Before Stein, network segment ranges were configured as an entry in ML2
> config file ml2_conf.ini that was statically defined for tenant network
> allocation and therefore had to be managed as part of the host
> deployment and management. When a regular tenant user creates a
> network, Neutron assigns the next free segmentation ID (VLAN ID, VNI
> etc.) from the configured segment ranges. Only an administrator can
> assign a specific segment ID via the provider extension.

Just for the record, here is an output after enabling the service plugin out of the box of Charmed OpenStack deployment.

This is not available on the charmhub still. A weird thing is that the charm build page has two built files.

https://launchpad.net/~openstack-charmers/charm-neutron-api/+charm/charm-neutron-api.master.latest/+build/1099
- neutron-api.charm does NOT have "enable-network-segment-range" option
- neutron-api_ubuntu-20.04-amd64.charm does have "enable-network-segment-range" option

However, when executing the following command, it downloads a charm WITHOUT enable-network-segment-range.

$ juju download --arch amd64 --series focal --channel yoga/edge neutron-api

[Alex Kavanagh (ajkavanagh)]

I think I've worked out what is going on here. The repository for neutron-api has had "neutron-api.charm" merged into it by accident, and that is (attempted) to be being uploaded: https://launchpad.net/~openstack-charmers/charm-neutron-api/+charm/charm-neutron-api.master.latest/+build/1099, in particular:

"Charmhub upload failed: Cannot insert package. An upload with that digest (SHA3-384: '3dd3d460ea5f234dfde56766b365524631b0d323c27cc0f1f177dbc3ee86617345e1a1b3635fd033bf02767a8640749d') already exists in the database."

I've raised a patch: https://review.opendev.org/c/openstack/charm-neutron-api/+/833990 to remove it from the archive. Just need it to land and hopefully that will solve this problem.

[Nobuto Murata (nobuto)]

Hi Alex, thank you for the detailed response. I suppose I need to be a bit more patient now to see a new job in https://launchpad.net/~openstack-charmers/charm-neutron-api/+charm/charm-neutron-api.master.latest

There are multiple issues just for the record.

latest/edge has the expected patch set which is good.

However, Juju is failing to pick it (might be a charmhub issue though):

Backport to xena branch has been merged on March 25th. But somehow it doesn't show up in `juju info` while it can be seen in `charmcraft status` for the owners.
