PROFILE
Purna Pavan Chandra
Worked on the microsoft/lisa repository to enhance Linux system automation and device management. Developed a dynamic data disk detection mechanism for Cloud Hypervisor test automation, using Python to query and select unmounted disks at runtime, which improved test reliability after VM reboots. Delivered a kernel installer feature that automated GRUB menu entry creation and enabled customizable boot configurations, streamlining kernel management across deployments. Added PCI_NVME device pool support in libvirt, including logic to exclude root-mounted NVMe devices, and refactored device pool code for clarity and maintainability. Demonstrated skills in Linux system administration, backend development, and test automation throughout these projects.

Jan 1, 2025January 2025 monthly summary for microsoft/lisa: Implemented a reliability fix in Cloud Hypervisor test automation by dynamically discovering an unmounted data disk instead of relying on a static 'datadisk_name'. This change prevents test preparation failures when VM disk paths change after reboot, improving test stability and CI reliability. The change is committed as 4b8bca855ea5463585e7e08a73bed1bee753c238 with message 'ch_tests: dynamically determine data disk path (#3583)'.
