## What it is
Source code accompanying a multi-part tutorial series on building an Intel VT-x hypervisor from scratch. It covers VMX operation, VMCS setup, EPT-based address translation, and virtualizing an already-running system.

## Use cases
- learn how to write a hypervisor from scratch
- understand Intel VT-x and VMX operation
- implement EPT address translation
- virtualize an already running Windows system
- use EPT page-level monitoring to detect code execution
- study hidden hooks and hypervisor-based techniques

## When to choose
- you want to learn low-level x86 virtualization internals step by step
- you need working C/C++ reference code for VMX, VMCS, and EPT
- you are preparing for hypervisor-based reverse engineering or security research

## When to avoid
- you need a production-ready hypervisor or VM platform
- you target hardware other than Intel VT-x on Windows
- you just want to use a hypervisor for debugging rather than build one (use HyperDbg instead)

## Facets
- artifact type: learning-resource
- maturity: stable
- function: simulation, security, developer-tools
- domain: tutorials, operating-systems, security, reverse-engineering
- platform: windows, cpp, c
- tags: hypervisor, vt-x, vmx, ept, virtualization, tutorial-series, kernel-driver, x86
