Bareflank is an open-source hypervisor SDK written in C++ (with Rust support) for rapidly prototyping custom hypervisors on 64-bit Intel and AMD CPUs, running on Windows, Linux, and UEFI. It provides only enough virtualization support to start and stop a hypervisor, serving as scaffolding for education, research, or building a full hypervisor like MicroV.
Use cases
- build my own hypervisor from scratch
- learn how hypervisors and VT-x work
- prototype virtualization research on Intel/AMD
- minimal hypervisor SDK for education
- create a type-1 hypervisor for Windows and Linux
- experiment with bare-metal virtualization in C++
When to choose
- you want to learn hypervisor internals or conduct virtualization research
- you need a clean, well-tested (100% unit coverage, AUTOSAR-compliant) foundation to build a custom hypervisor
- you need cross-OS support including UEFI
When to avoid
- you need a complete, fully functional hypervisor today (use MicroV or SimpleVisor instead)
- you need production VM hosting with device passthrough, live migration, etc.
- you need ARM, RISC-V, or PowerPC support (only planned)
