- Read the relevant code before proposing or making changes. Keep changes focused, preserve existing structure where practical, and avoid unrelated renames or refactoring. - Use a written plan for genuinely multi-stage work or when the user requests one. Store repository plans in PLAN.md, and obtain approval before implementing a plan that introduces significant design choices. - Match validation effort to the risk and scope of the change. Establish a relevant baseline before broad or high-risk work; small changes may…

OpenVMM is a modular, cross-platform Virtual Machine Monitor (VMM) written in Rust. This repository is home to both OpenVMM and OpenHCL (a paravisor). Documentation lives in Guide/ and is published at https://openvmm.dev. Restore required dependencies before building for the first time: The project supports cross-compilation for x86_64 and aarch64. OpenHCL can only be built from Linux (WSL2 counts). For cross-compilation from WSL2 to Windows, see Guide/src/dev_guide/getting_started/cross_compile.md and source . ./build_support/setup_windows_cross.sh. For .proto changes (including gRPC/ttrpc), read and follow the Protocol…

These instructions define how GitHub Copilot should assist with this project. The goal is to ensure consistent, high-quality code generation aligned with our conventions, stack, and best practices. - Code Style: The project uses an .editorconfig file to enforce coding standards. Follow the rules defined in .editorconfig for indentation, line endings, and other formatting. Additional information can be found on the wiki at Implementation. The code requires C++11/C++14 features. Notable .editorconfig rules: C/C++ files use 4-space indentation, crlf line endings,…

Always use conventional commits format when creating commits. Follow this structure: The scope should indicate the package or area affected (e.g., library, yaml-reader, hidi). If a commit introduces a breaking change, add BREAKING CHANGE: in the footer or append ! after the type/scope: The user might request you update the benchmark information. You might do it on your own if a previous change added new properties to models under src/Microsoft.OpenApi/Models. Always use a separate commit for this change. To do…
