Fixed — anchored to $1 ~ /^rhos/ in c20f30c. Verified on live RHEL 10.2 node: both patterns match the same 22 repos (all rhos-release and rhosp-* IDs), rhelosp-ceph-* correctly excluded by both.

These two blocks roles/repo_setup/tasks/rhos_release.yml and roles/reproducer/tasks/rhos_release.yml are nearly identical (same repo-discovery awk, same exclude logic).
The suggested fix is to pull the shared logic out into its own small, focused role — following the pattern already used throughout ci-framework.
New role: roles/cifmw_rhel10_repo_guard/
# roles/cifmw_rhel10_repo_guard/defaults/main.yml
cifmw_rhel10_repo_guard_repo_pattern: '^rhos'
cifmw_rhel10_repo_guard_exclude_globs: "python3*,python3-libs*"
cifmw_rhel10_repo_guard_extra_packages: [] # e.g. [gcc, python3-devel] when a caller needs build deps too

Agreed on the DRY principle — the shared awk+exclude logic is a good extraction candidate. However the two blocks have meaningful differences that make a direct extraction tricky:
- Disable scope: repo_setup disables only
rhos-release-extras; reproducer disables 6 additional repos (rhosp-rhel-9.4-{appstream,baseos,fdp-cdn,ha,image-build-override}) - Base repo setup: reproducer creates RHEL 10 base repos via
yum_repository(compute VMs don't have them); repo_setup doesn't need this (hypervisor already has base repos) - Package module: The proposed role uses
ansible.builtin.package, which breaks on compute VMs whereansible_facts['pkg_mgr']isn't gathered — thepkg_mgrbug this push fixes (see build d69d8ad4). Must useansible.builtin.dnffor hosts without gathered facts.
I'd suggest merging the current fixes (awk anchoring + dnf) to unblock the pipeline, then extracting the shared role as a follow-up with proper parameterization for these differences. WDYT?

Five fixes for RHEL 10 hypervisor and VM support, all gated by ansible_distribution_major_version >= 10 (no RHEL 9 regression): 1. dnsmasq: Version-conditional PID file path (/run vs /var/run) due to RHEL 10 inverted SELinux fcontext equivalency. 2. repo_setup: Exclude python3* from rhos-release repos to prevent el9 python3 overriding RHEL 10 python3.12. 3. repo_setup: Disable rhos-release-extras repo on RHEL 10+ (404s on $releasever=10). Install python3-setuptools, gcc, python3-devel (missing on RHEL 10 by default). 4. reproducer: Same RHEL 10 protections as repo_setup for VMs (python3 exclude, repo disable, setuptools install). 5. reproducer: Configure RHEL 10 BaseOS and AppStream repos on VMs after rhos-release strips usable repos. Without this, VMs have zero RHEL 10 repos for basic packages (bash-completion, vim, etc.). Validated on live serval64 environment: control plane deploys successfully (37/39 conditions Ready) with these fixes.

Protect repository transport and package verification.
Both roles fetch repository content over HTTP and disable RPM signature checks. An on-path attacker can replace repository metadata and RPMs. The subsequent root DNF task can then install attacker-controlled code.

Disable only the unavailable repository.
These globs disable every enabled repository in the generated RHOS and OSP files. This disables the primary release repositories that rhos-release configured. The stated RHEL 10 behavior disables rhos-release-extras only.

Summary
Four fixes for RHEL 10 hypervisor support, all gated by
ansible_distribution_major_version >= 10(no RHEL 9 regression).1. dnsmasq: Version-conditional PID file path
RHEL 10 inverted the SELinux file context equivalency from
/run = /var/runto/var/run = /run. Setting fcontext on/var/run/paths now fails:Verified in Zuul build 2c922ff6 (line 2992). The systemd unit already uses
/run/cifmw-dnsmasq.pid.Fix uses Jinja2 conditional:
/run/on RHEL 10+,/var/run/on RHEL 9 (original behavior preserved).2. repo_setup: Exclude python3 from rhos-release repos
rhos-releaseconfigures RHEL 9 repos on RHEL 10 hypervisors. Installingnmstate(el9) pullspython3-libnmstatewhich requirespython3.9dist(pyyaml)(verified viarpm -qR), causing dnf to downgradepython3from 3.12 to 3.9 (confirmed in/var/log/dnf.logon serval64).This breaks 9 RHEL 10 system tools whose shebangs use
#!/usr/bin/python3 -sP— the-Pflag requires Python 3.11+:firewalld,firewall-cmd,firewall-offline-cmdjsonschema,normalizer,distroactivate-global-python-argcomplete,register-python-argcomplete,python-argcomplete-check-easy-install-scriptFix uses
dnf config-manager --setopt=REPO.exclude=python3*,python3-libs*on all rhos-release repos.3. repo_setup: Disable rhos-release-extras on RHEL 10+
The
rhos-release-extrasrepo uses$releasever(=10 on RHEL 10) but the server has no RHEL 10 content (HTTP 404 at line 7561). This causesdevscripts make requirementsto fail.4. repo_setup: Install python3-setuptools on RHEL 10+
RHEL 10 does not ship
python3-setuptoolsby default (RHEL 9 did). Ansible's built-inpipmodule (ansible/modules/pip.py:281) importsfrom pkg_resources import Requirement—pkg_resourcesis part ofsetuptools. When the inner reproducer runsansible.builtin.pipon the hypervisor to install dev-scripts Python dependencies, it fails withModuleNotFoundError: No module named 'pkg_resources'.SSH-verified on serval64 (RHEL 10.2):
rpm -qa | grep setuptoolsreturns empty,python3 -c "import pkg_resources"fails. Afterdnf install python3-setuptools(69.0.3 from rhel-10-baseos): import succeeds.Verification
