Mar 1, 2026March 2026 monthly summary: Focused documentation enhancements in the doctor-cluster-config repository to improve hardware accuracy for deployment. Corrected NIC counts in the Expansion Card Documentation and added Mellanox ConnectX-7 details, aligning hardware specs with deployment guidance. This reduces misconfigurations, shortens troubleshooting cycles, and supports reliable cluster provisioning for customers using newer NICs. Delivered via a targeted documentation update and one commit (2753cdc23239a50a03c0834882588b8bcdd3460f).

Sep 1, 2025Month: 2025-09 — Delivered targeted SVSM kernel and host module upgrades for jamie in the doctor-cluster-config repository, enhancing security posture and hardware capabilities. Replaced the generic Nix SVSM module with a wallet-specific module, removed the Nvidia module, and upgraded the SVSM kernel to the latest version with VFIO_DEVICE_CDEV support. These changes improve security, device passthrough reliability, and maintainability, and align with platform hardening goals.
