Zhanb contributed to the microsoft/MigTD repository by developing and enhancing Azure CVM emulation capabilities, enabling robust testing and development of TDX migration features without requiring physical TDX hardware. Using Rust and C, Zhanb implemented VMCall Raw Transport support, introduced AzCVMEmu for emulating TDX calls and TCP networking, and aligned the emulation layer with evolving GHCI 1.5 specifications. The work included improvements to build systems, dependency management, and CI/CD workflows, as well as updates to documentation and logging for better maintainability. These efforts deepened test coverage, streamlined migration validation, and improved the reliability of secure system programming workflows.

October 2025 — Delivered GetReportData support in AzCVMEmu and enabled TD report generation via vTPM for MigTD. Implemented CLI enhancements to expose migration and getreport modes, refactored the emulation layer to handle new request types, and aligned with GHCI 1.5 changes. This work enables end-to-end migration validation and reporting, improving test coverage and data-driven decision-making.

September 2025 monthly summary for microsoft/MigTD: Delivered Azure CVM Emulation Mode (AzCVMEmu) to MigTD testing, enabling TCP-based emulation of TDX TDcalls and related interfaces in CI and reducing the need for a physical TDX environment. Updated CI workflow and dependencies and removed an unnecessary patch file to streamline the test setup. Implemented GHCI 1.5 compatibility fixes in the tdx_emu emulation layer to align with upstream changes, including buffer parsing/formatting adjustments for new GHCI 1.5 structures and ensuring correct data handling for migration-related TD VMCALLs. Improved log readability by appending newline characters to log entries for clearer debugging and monitoring.
