Worked on the virt-s1/os-tests repository to enhance Azure VM lifecycle management and test reliability. Over three months, delivered features such as configurable disk controller types for Azure VMs, enabling SCSI or NVMe selection to optimize storage performance and deployment flexibility. Improved VM creation with distinct nametags and SR-IOV support, and strengthened deletion logic to handle missing user data gracefully. Refined ARM crashkernel memory allocation and updated test environments for RHEL 8+ and 10+, reducing flakiness and improving diagnostics. Leveraged Python, YAML, and shell scripting to implement infrastructure as code, configuration management, and robust test automation across cloud environments.

Mar 1, 2025March 2025 focused on delivering configurable Azure VM storage performance enhancements for virt-s1/os-tests and preparing the ground for broader cloud storage tuning. Implemented a new disk_controller_type parameter in the Azure configuration, enabling administrators to select SCSI or NVMe disk types during VM provisioning. This change integrates into the VM resource creation workflow and is backed by a dedicated commit. No major bugs were reported for virt-s1/os-tests in this period. Overall, this work improves deployment flexibility, performance optimization opportunities on specific VM series, and reduces manual configuration effort for storage tuning.
