## What it is
hvpp is a lightweight Intel VT-x hypervisor written in modern C++ that virtualizes an already-running operating system, primarily targeting Windows. It serves as a compact, well-documented reference implementation for learning x64 hardware virtualization, EPT, and hypervisor-based introspection.

## Use cases
- learn how Intel VT-x hypervisors work
- build a hypervisor-based sandbox for Windows
- hide a process or hook code using EPT
- study VMX and EPT internals with readable C++ source
- virtualize an already running OS without a full VMM
- research anti-cheat and anti-VM detection techniques

## When to choose
- you want a small, readable C++17 codebase to study VT-x virtualization
- you need a Windows-focused type-1-style hypervisor that runs on an already booted OS
- you're doing security research involving EPT-based introspection or stealth

## When to avoid
- you need a production hypervisor for running multiple guest VMs
- you need cross-platform support beyond Windows
- you need actively maintained code with recent releases and support
- you're not comfortable with kernel-level development and debugging

## Facets
- artifact type: library
- maturity: maintenance
- function: security, reverse-engineering, developer-tools
- domain: security, operating-systems, reverse-engineering, developer-tools
- platform: windows, cpp
- tags: hypervisor, vt-x, ept, vmx, introspection, sandbox, kernel-driver, educational, virtualization, x64
