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). But if you want to do it the way I did then please feel free to use my setup above.

Initial Steps

• Open VirtualBox

  

• Right-click your VM, then click Settings

  

• Go to Shared Folders section

  

• Add a new shared folder

  

• On Add Share prompt, select the Folder Path in your host that you want to be accessible inside your VM. Type shared for the Folder Name. Make sure that Read-only and Auto-mount are unchecked and Mount point is blank. Then click OK.

  

• Start your VM

  

• Once your VM is up and running, go to Devices -> Insert Guest Additions CD image

  

• Use the following command to mount the CD

  sudo mkdir /media/cdrom
  sudo mount -t iso9660 /dev/cdrom /media/cdrom
  

• Install dependencies for VirtualBox guest additions

  sudo apt-get update
  sudo apt-get install -y build-essential linux-headers-`uname -r`
  

• Run the installation script for the guest additions. Wait until the installation completes.

  sudo /media/cdrom/./VBoxLinuxAdditions.run
  

• Reboot VM

  sudo shutdown -r now
  

• Create shared directory in your home

  mkdir ~/shared
  

• Mount the shared folder from the host to your ~/shared directory

  sudo mount -t vboxsf shared ~/shared
  

• The host folder should now be accessible inside the VM.

  cd ~/shared
  

Make the mount folder persistent

This directory mount we just made is temporary and it will disappear on next reboot. To make this permanent, we'll set it so that it will mount our ~/shared directory on system startup

• Edit fstab file in /etc directory

  sudo nano /etc/fstab
  

• Add the following line to fstab (separated by tabs). Make sure to replace <username> with your username. Save the file.

  shared	/home/<username>/shared	vboxsf	defaults	0	0
  

• Edit modules

  sudo nano /etc/modules
  

• Add the following line to /etc/modules and save

  vboxsf
  

• Reboot the VM and log-in again

  sudo shutdown -r now
  

• Go to your home directory and check to see if the directory is highlighted in green.

  

If it is then congratulations! You successfully linked the directory within your VM with your host folder.
