Guest Additions are designed to be installed inside a virtual machine after the guest operating system has been installed.
They comprise device drivers and system applications that optimize the guest operating system for better performance and usability. For installing the VirtualBox guest additions you need to open the terminal. At the start option search for the terminal, once the terminal result comes you just need to click on the terminal option. Once your terminal opens you just need to type the command below and press enter, it will ask for your Ubuntu password enter your Ubuntu password, then press Y yes.
This is to install some essential packages before you install VirtualBox guest additions on your Ubuntu to the operating system.
After some time, you see all the installation steps are finished. Once it's done, you can close your terminal. The second step is to install guest additions for this you will need to mount the Guest Additions CD. We can do this from within VirtualBox. If you have done this step previously and it is already mounted, you need to find out the location where it is mounted. For this you need to use the following commands:.
Also Read: Ifconfig Command in Linux. It will open a terminal window as shown in the below figure from which the actual installation of VirtualBox Guest Additions will happen. Once the installation completes, press Enter to close the installer terminal window.
If a Windows Security dialog is displayed that prompts you to install device software see Figure 6. When the Guest Additions installation is complete, ensure Reboot now is selected see Figure 6. When the virtual machine reboots, log in. Next, you need perform some additional configuration in the virtual machine, as described in Section 6.

On some Windows versions, such as Windows and Windows XP, the user intervention popups mentioned above are always displayed, even after importing the Oracle certificates. Installing the code signing certificates on a Windows guest can be done automatically. Use the VBoxCertUtil. This command installs the certificates to the certificate store.
When installing the same certificate more than once, an appropriate error will be displayed. To allow for completely unattended guest installations, you can specify a command line parameter to the install launcher:. This automatically installs the right files and drivers for the corresponding platform, either bit or bit.
By default on an unattended installation on a Vista or Windows 7 guest, there will be the XPDM graphics driver installed. Instead, the WDDM graphics driver needs to be installed. This is only required for Vista and Windows 7. For more options regarding unattended guest installations, consult the command line help by using the command:. If you would like to install the files and drivers manually, you can extract the files from the Windows Guest Additions setup as follows:.
To explicitly extract the Windows Guest Additions for another platform than the current running one, such as bit files on a bit system, you must use the appropriate platform installer. Use VBoxWindowsAdditions-x The Guest Additions work in those distributions. You may choose to keep the distribution's version of the Guest Additions but these are often not up to date and limited in functionality, so we recommend replacing them with the Guest Additions that come with Oracle VM VirtualBox.
The Oracle VM VirtualBox Linux Guest Additions installer tries to detect an existing installation and replace them but depending on how the distribution integrates the Guest Additions, this may require some manual interaction.
It is highly recommended to take a snapshot of the virtual machine before replacing preinstalled Guest Additions. See Section 4. They also come with an installation program that guides you through the setup process.
However, due to the significant differences between Linux distributions, installation may be slightly more complex when compared to Windows. Before installing the Guest Additions, you prepare your guest system for building external kernel modules. This works as described in Section 2. If you suspect that something has gone wrong, check that your guest is set up correctly and run the following command as root:. Insert the VBoxGuestAdditions. Org variant of the system, or XFree86 version 4. Org release.
During the installation process, the X. Org display server will be set up to use the graphics and mouse drivers which come with the Guest Additions. After installing the Guest Additions into a fresh installation of a supported Linux distribution or Oracle Solaris system, many unsupported systems will work correctly too, the guest's graphics mode will change to fit the size of the Oracle VM VirtualBox window on the host when it is resized.
You can also ask the guest system to switch to a particular resolution by sending a video mode hint using the VBoxManage tool. Multiple guest monitors are supported in guests using the X.
