Intel VT-x Hypervisor

Description:
A low-level systems project focused on building a custom hypervisor using Intel VT-x virtualization technology. This project explores hardware-assisted virtualization, VMX operation, guest and host state management, memory handling, and the foundations of secure and efficient virtual machine control.

"To understand the machine completely, you must step beneath the operating system and speak the language of the processor."

Body

The Intel VT-x Hypervisor project is an exploration of virtualization at the hardware level. Its purpose is to study and implement a minimal hypervisor that can interact directly with Intel’s VMX architecture, enabling control over virtual machine execution from a privileged layer beneath the operating system.

This project covers core concepts such as entering and leaving VMX operation, configuring VMCS structures, handling VM exits, managing CPU state transitions, and understanding how the processor separates host and guest environments. It also serves as a practical way to learn how modern virtualization platforms work internally.

Beyond technical implementation, this project represents a deeper investigation into operating system internals, processor behavior, and system security. By working with Intel VT-x, the project aims to build both a functional hypervisor prototype and a stronger understanding of the boundary between hardware and software.

Why this project

Virtualization is one of the core technologies behind modern cloud computing, sandboxing, malware analysis, and system isolation. Building a hypervisor from scratch provides valuable insight into how systems can be controlled, monitored, and secured at the lowest level
