VT Debugger Quick Start Guide
This guide gets you running the VT Debugger in 10 minutes: check environment → install driver → attach target → set breakpoints → debug invisibly.
Check System Requirements
Windows 10/11 x64, CPU with Intel VT-x or AMD-V (enabled in BIOS), run as administrator.
Tip: Inside a VM, the host must enable nested virtualization; Hyper-V coexistence is unsupported (disable VBS).
Download & Extract
Download the latest archive from the official page and extract to a path without Chinese characters or spaces (e.g., C:\VT).
Tip: Non-ASCII paths can break driver loading.
Install the Driver
Run the install script as administrator or click 'Load Driver' to install the RING0 driver service.
Tip: If signature verification fails, temporarily disable driver signature enforcement via Advanced Startup.
Launch & Attach
Launch the VT Debugger, click 'Attach Process' to pick the target (or enter a PID); virtualization initializes automatically.
Tip: The target is not paused until initialization completes; pause it first if needed.
Set Your First Breakpoint
Locate a code address in the disassembly/memory view (e.g., a function entry) and choose 'Set Invisible Breakpoint'.
Tip: Breakpoints use EPT page permissions; multiple breakpoints per page work independently.
Debug & Troubleshoot
On hit, inspect registers/memory and step; if not hit, verify the address or try a hardware breakpoint.
Tip: Common issues: driver not loaded (check service), VT claimed by Hyper-V (disable VBS), optimized address (use module base + offset).
