Introduction

This tutorial will walk you through the steps required to compile libmicrovmi and run the mem-dump Rust example code on a Xen domain in order to dump its physical memory.

This tutorial assumes the following:

• you have a working installation of Rust as well as a Xen domain
• you have a running VM supervised by Xen 4.11.0 or above.
• you are running on Ubuntu 20.04

Requirements

• clang (bindgen)
• Xen development headers

To install the additional dependencies:

$ sudo apt install clang libxen-dev

Cloning libmicrovmi

Before beginning the tutorial, clone the repo:

$ git clone https://github.com/Wenzel/libmicrovmi

⚠️ Note: Accessing Xen's introspection APIs will require high privileges as we are talking to Dom0, hence we have to run cargo as root when actually running and testing example code.
