PROFILE
Manuel Huber
Manuel Hernandez contributed to the DataDog/kata-containers repository by engineering robust NVIDIA GPU integration and security automation for confidential and cloud-native environments. Over three months, he developed and validated CUDA and VFIO GPU passthrough support, automated policy generation, and enhanced CI infrastructure to streamline GPU-enabled deployments. His work leveraged Bash and Go for scripting and system programming, focusing on containerization, Kubernetes integration, and security best practices. By addressing driver conflicts, refining build systems, and implementing automated attestation and policy controls, Manuel improved deployment reliability and compliance. His contributions demonstrated depth in DevOps, GPU programming, and secure, scalable infrastructure engineering for production workloads.

16 Commits • 3 Features
Dec 1, 2025December 2025 — DataDog/kata-containers: focused on hardening NVIDIA GPU support and automating security policy generation. Key work included VFIO GPU passthrough validation in the security policy, enabling NVIDIA GPU passthrough and paving the way for other VFIO devices; and implementing automated policy generation and security controls for NVIDIA TEE GPUs in CI, including pod security policies, attestation settings, and tests for confidential hardware. Also delivered CI/test infrastructure improvements for NVIDIA GPU testing to improve reliability, reduce rate limits, and secure NVNG/NVCR-based image sources. These efforts strengthen security compliance, reduce deployment risk for GPU-enabled workloads, and improve CI stability, accelerating delivery of GPU-enabled features across the stack.

Oct 1, 2025October 2025 (DataDog/kata-containers) delivered key NVIDIA GPU capabilities and confidential-environment readiness, focusing on reliability, scalability, and maintainability of NVIDIA-enabled deployments. Key features include a CUDA vector-add test to validate CUDA environment setup and vector operations, with NVRC tracing made optional and idempotent and a skip-path for multi-GPU tests in single-GPU environments to improve CI reliability and workload flexibility. NVIDIA rootfs and build script improvements add guest pull support components and standardize rootfs variant naming to resolve local build inconsistencies in confidential contexts. Fixed driver install conflicts by removing version suffixes for imex and libnvidia-nscq and eliminated CDI leakage by clearing outer CDI annotations to ensure proper device injection and runtime stability. These changes reduce installation conflicts, improve build stability, and enhance runtime security for confidential workloads, while strengthening CI coverage and traceability across commits.
