Mar 1, 2026March 2026 focused on reliability, diagnostics, and test determinism for the os-autoinst-distri-opensuse workflow. Delivered targeted improvements to console handling, addon lifecycle reliability, and VM diagnostics, plus a workaround to stabilize SAP tuning tests for SLES 16. Result is faster feedback loops, reduced test flakiness, and clearer visibility into failures. Key outcomes include enhanced boot-time console handling (ensuring return key delivery to the SSH console and pre-activation of tty2/tty3/tty4), configurable timeouts for addon registration in PC, and improved diagnostic logging with timeout and fatal error support. A dedicated workaround was implemented for the SAP tuning test circular dependency to prevent suite-wide failures.

Aug 1, 2025August 2025: Implemented a robust retry mechanism for 'crm resource cleanup' in os-autoinst/os-autoinst-distri-opensuse. The change adds up to three retries for timeouts or 'no messages received', improving reliability of automated cleanup in the SLES for SAP public cloud module. Commit 0dcf8ef7d43917fe8928cd758da77a5c24e402d0 documents the fix. This reduces failure rates, lowers operational toil, and demonstrates fault-tolerant design in resource management.

Jul 1, 2025July 2025 monthly summary for os-autoinst/os-autoinst-distri-opensuse: Delivered two critical bug fixes improving Hyper-V VM detection and AutoYaST provisioning security patterns. Hyper-V Minimal VM Compatibility Update renames the svirt-hyperv-uefi entry to svirt-hyperv2022-uefi to align with newer Hyper-V versions and ensure correct VM environment detection, reducing test flakiness. SELinux Pattern Inclusion for AutoYaST adds the SELinux pattern to the agama configuration to ensure SELinux is included in Auto YaST software patterns, addressing bsc#1247046. These changes, committed in b9638c7928952215548515f8a858425f516ea6dd and ae4bd3f70de9c97dd30141e55ffc2ab3b0add7cc, respectively, improve deployment reliability and security posture across the operating system testing stack.
