December 2024 monthly summary: Delivered key features and reliability improvements across oxidecomputer/propolis and oxidecomputer/omicron, driving stability, simplification, and observability that directly support faster, reliable migrations and provisioning. Key features delivered: - Migration framework modernization and configuration centralization: refactored migration preamble to source-derived target specs, centralized migration failure injection into instance specifications, and introduced a dedicated propolis-config-toml crate to simplify server responsibilities. - API consolidation and flexible component identification: unified instance creation under a single instance_ensure API and introduced SpecKey to support component IDs as UUIDs or names; NVMe disk specs now include serial numbers. - Migrate in-memory block backends: added export/import capability, updated server initializer to register backends for lifecycle notifications, and introduced tests/utilities for Windows and Linux test execution. - NVMe tracing logging accuracy improvement: updated nvme-trace.d to log byte offsets and sizes rather than logical block numbers and counts, aligning with current probe definitions. - Propolis VM creation API integration: integrated with the new Propolis VM creation API, refactoring how instance specifications (disks, boot order) are handled and using explicit configuration and replacement lists during migrations to prepare for future virtual platform abstractions. Major bugs fixed: - Fixed NVMe tracing to report byte offsets/sizes, reducing interpretation errors and aligning with probe definitions. - Reduced server complexity by centralizing configuration parsing and moving migration failure injection into instance specs, improving stability and maintainability. - Improved cross-repo consistency and test coverage for migration-related backends on Windows and Linux. Overall impact and accomplishments: - Increased migration reliability and predictability through centralized configuration, unified APIs, and improved observability. - Lowered ongoing maintenance burden via streamlined configuration handling and a single, extensible API surface. - Strengthened preparedness for future virtualization abstractions and cross-repo collaboration through explicit configuration handling and API evolution. Technologies/skills demonstrated: - Rust-based server and API design, configuration management, and lifecycle-aware backend registration. - Cross-repo integration and API consolidation. - Test automation for Windows/Linux environments and enhanced observability through improved logging.

November 2024: Delivered a critical reliability improvement in oxidecomputer/propolis by addressing Linux guest terminal width handling for long commands. The change widens the effective terminal width using stty, and is backed by a framework test validating behavior across Linux distributions and Windows Server 2022, with explicit exclusions for older Windows Server versions that use a different terminal backend. This work reduces command-length related failures in Linux guest environments and enhances cross-OS automation reliability, contributing to smoother customer workflows and lower support burden.
