📝 Walkthrough

Summary by CodeRabbit

• New Features

  • Added support for provisioning RHEL 9.6 and RHEL 10 virtual machines on s390x.
  • Added container-engine groups to generated inventories.

• Bug Fixes

  • Improved cleanup handling when virtual machines, floating IPs, or security groups are already unavailable.
  • Expanded cockpit shutdown handling for s390x environments and port conflicts.

• Documentation

  • Updated the supported s390x RHEL VM family list.

Walkthrough

The Ansible configuration now supports RHEL 8.6, 9.6, and 10 s390x VM families. VM creation selects family-specific images and adds a container engine inventory group. Destruction tolerates not-found errors, and cockpit handling includes s390x.

Changes

s390x VM lifecycle updates

Layer / File(s)	Summary
Image configuration and VM creation ansible/vars/s390x.yml, ansible/group_vars/all.yml, ansible/roles/create-vm/..., ansible/README.md	The configuration and documentation list the RHEL 9.6 and RHEL 10 s390x families. VM creation selects the image from s390x.image_ids and adds the container engine inventory group.
Resource destruction ansible/roles/destroy-vm/tasks/destroy-s390x-vm.yml	VM and floating IP deletion tolerate errors. Security group deletion uses the inventory-derived name and VPC, and accepts not-found responses.
Cockpit provisioning ansible/roles/provision-vm/tasks/redhat.yml	The cockpit socket disable task now applies to s390x and documents collector port and RHEL Web Console conflicts.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 0f843

The PR adds RHEL 9.6 and RHEL 10 s390x CI images, but cleanup failures may leave orphaned resources and cockpit shutdown failures may prevent the collector from binding port 9090. These availability and lifecycle risks should be fixed before merging.

Hi @jdao-rh, sorry for the delay reviewing this. It looks like you are hitting some auth issues similar to the ones in #3390 w.r.t the location of podman authorization files, can you try to pull the changes needed and see if the test runs? I can help you pinpoint what is needed.

[Molter73]

Thanks for this @jdao-rh! The PR looks good, I have just one last question about the RHEL 9 version. The changes seem to suggest we should be using RHEL 9.6, however, when I check the collector logs in the tests I see that it is actually using RHEL 9.2, is this expected/can we do something about it?

Still need to address one question

Oh good catch, I will check that image i uploaded for rhel 9. Will update to a rhel 9.6 image

[jdao-rh]

@Molter73 The image has been updated to rhel 9.6. However now the CI is running 3 versions of RHEL, and I find the testing to a bit flaky (had to retry for this pr's tests to pass).

- Line 22: Replace the broad ignore_errors settings in the VM and floating-IP
deletion tasks with failed_when conditions that ignore only documented not-found
responses, while propagating authentication, validation, dependency, and
transient API failures. Follow the existing Security Group task’s conditional
handling pattern and preserve inventory cleanup only after deletion succeeds or
is confirmed absent.

In `@ansible/roles/provision-vm/tasks/redhat.yml`:
- Around line 67-75: Update the “Disable cockpit socket” task to stop
suppressing all systemd failures: tolerate only the missing-unit case, while
propagating other failures and verifying that cockpit.socket is stopped and
disabled. Preserve the ppc64le and s390x condition and ensure provisioning fails
if the socket remains active or enabled.
