Virtual Box Notes

Virtual Box

To install VirtualBox Guest Additions on a GUI-less Ubuntu Server

1. Install prerequisites Open a terminal in your Ubuntu Server guest and run these commands to install the required packages:

sudo apt update
sudo apt install dkms build-essential linux-headers-$(uname -r)

2. Insert and mount the Guest Additions CD image From the VirtualBox menu on your host machine, go to Devices and select Insert Guest Additions CD image… The CD image should appear in your server’s file system, often under /media/cdrom or a similar path. Mount the CD image if it’s not automatically mounted:

sudo mkdir /media/cdrom
sudo mount /dev/cdrom /media/cdrom

3. Run the installation script Navigate to the mounted directory: Run the installer script. You may need to switch to the root user first for a GUI-less server:

cd /media/cdrom
sudo ./VBoxLinuxAdditions.run

4. Restart the virtual machine Restart the guest machine for the changes to take effect:

sudo reboot

sudo usermod --append --groups vboxsf -- "$USER"
