Mar 1, 2026March 2026 performance highlights: Expanded OCI testing coverage and hardened FIPS-mode boot handling within the virt-s1/os-tests framework. Delivered OCI configuration, provisioning scaffolding, and resource management capabilities for VMs and storage, including attach/detach operations for block devices and NICs in OCI. Fixed boot partition UUID retrieval under FIPS mode by aligning the retrieval to the actual boot device, reducing boot-related failures in secure deployments. These changes broaden cloud validation, improve reliability for OCI and FIPS scenarios, and demonstrate end-to-end cloud-testing and provisioning capabilities.

Oct 1, 2025Month: 2025-10 — Focused on reliability improvement in auto-registration flow for virt-s1/os-tests. Replaced output parsing with return-status check of subscription-manager status (0 indicates success) inside enable_auto_registration, reducing flakiness in CI and deployed environments. The change was implemented via the patch that applies the commit "Fix subscription-manager status return status" (commit hash c28e17c5d612b06104c52b203b3659e85651e314).

Jan 1, 2025January 2025 monthly summary for virt-s1/os-tests focused on FIPS compliance for RHEL10 image mode. Delivered a robust fix to enable FIPS across all RHEL image types by adding a conditional path for ostree-based images to use rpm-ostree kargs, while preserving grubby for non-ostree systems. This ensures FIPS is consistently enabled across image modes and reduces risk of misconfiguration.
