Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
Microsoft Windows 7 SP1 as the host OS
A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

Update 28 July 2019: An updated version of this guide for Ubuntu Server 18.04 LTS is now available. Feel free to check it out.

Update 23 May 2020: This guide is ALREADY OUTDATED and might no longer work with new versions of Ubuntu and VirtualBox. Please consider switching to the updated guide instead. I will no longer respond to the replies to this gist. Thank you.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs
