# Memory dump example on Xen
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 cargo stable toolchain
- 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
~~~
⚠️ 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.
