No module named 'ansible.module_utils.openstack'

[Cédric Jeanneret]

Hello,

While doing node provisioning with metalsmith on my fresh master deploy, I hit the mentioned issue.

It comes from:
https://opendev.org/openstack/metalsmith/src/branch/master/metalsmith_ansible/ansible_plugins/modules/metalsmith_instances.py#L398-L400

If we check the top of that file, we can see the actual import exception is "masked" - so I edited the file, removing the try/except in order to display the actual python error:

2022-03-31 04:41:33.480636 | 24420198-6297-967d-b366-000000000017 | TASK | Reserve instances
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ModuleNotFoundError: No module named 'ansible.module_utils.openstack'

This happens in my lab, but I'm pretty sure CI will hit it sooner or later.

Here are the involved versions:
python3-metalsmith-1.6.2-0.20220223192700.264836d.el9.noarch
ansible-role-metalsmith-deployment-1.6.2-0.20220223192700.264836d.el9.noarch
ansible-collections-openstack-1.7.2-0.20220323165949.7b26b82.el9.noarch

Weird thing is: packages are pretty old - minimum a week, and I'm using the tripleo-ci-testing line.

False flag. It *is* mitogen. Setting the strategy to "linear" makes it pass.
