184.108.40.206. Installing the Linux Guest Additions
The VirtualBox Guest Additions for Linux are provided on the same virtual CD-ROM file as the Guest Additions for Windows described above. They also come with an installation program guiding you through the setup process, although, due to the significant differences between Linux distributions, installation may be slightly more complex.
Installation generally involves the following steps:
Before installing the Guest Additions, you will have to prepare your guest system for building external kernel modules. This works similarly as described in Section 2.3.2, “The VirtualBox kernel module”, except that this step must now be performed in your Linux guest instead of on a Linux host system, as described there.
Again, as with Linux hosts, we recommend using DKMS if it is available for the guest system. If it is not installed, use this command for Ubuntu/Debian systems:
sudo apt-get install dkms
or for Fedora systems:
yum install dkms
Be sure to install DKMS before installing the Linux Guest Additions. If DKMS is not available or not installed, the guest kernel modules will need to be recreated manually whenever the guest kernel is updated using the command
Insert the VBoxGuestAdditions.iso CD file into your Linux guest's virtual CD-ROM drive, exactly the same way as described for a Windows guest in Section 220.127.116.11, “Installation”.
Change to the directory where your CD-ROM drive is mounted and execute as root:
