This is a research hypervisor written as a UEFI and Windows driver for the educational purpose for Intel processors. This is a research hypervisor written as a UEFI and Windows driver for the educational purpose for Intel processors.
This MiniVisor, as a UEFI driver, provides the ability to inspect system activities even before the operating system boots, while as a Windows driver, allows developers to debug it with familiar tools like WinDbg.

Given the universality of UEFI systems on the AMD64 ecosystem and the unique ability to monitor, attack and protect the system throughout operating system startup on bare-metal systems, the authors believe that having the understanding and being able to develop this type of hypervisors are valuable for research.

With this goal in mind, the project aims to offer
- Straightforward and approachable codebase
- over highly-abstracted but intricate structures
- Rich comments aimed for new learners
- over just-enough for those who already know how hypervisor works
- Minimal functionality to highlight core concepts to study
- over extensibility and direct usefulness
- Extensive documentation on development environment setup
