Installing Virtualbox Guest Additions on SUSE Linux Enterprise Server 12 and 15

 This article is not a complete and detailed how to, but will covered the subtlety of installing and using the Virtualbox Guest Additions (or Virtualbox Tools) on SUSE Linux Enterprise Server 12 SPX and SUSE Linux Enterprise Server 15 SPX.

Requirement:

Packages : gcc make kernel-default-devel

And of course you need to add the CD image of the Virtualbox Guest Additions in your SLES Virtual Machine :

Devices -> Insert Guest Additions CD image

Step :

1) Mount the cd image:

# mount /dev/sr0 /mnt

2) Install the package requirement:

# zypper in gcc kernel-default-devel

3) Enable "unsupported modules" to be loaded in the SLES's kernel:

Edit /etc/modprobe.d/10-unsupported-modules.conf

and set: allow_unsupported_modules 1

 

4) Run the Virtualbox Guest Additions installation script:

# cd /mnt

# ./VBoxLinuxAdditions.run
Verifying archive integrity... All good.

5) You can now reboot your system and check the if the new modules are used:

# reboot

and then after the reboot: 

# lsmod | grep vbox vboxsf                 47920  0 vboxvideo              12669  1 drm                   322623  2 vboxvideo vboxguest             298126  3 vboxsf
