VirtualBox 3.2.12 + openSUSE 11.2 + VBoxLinuxAdditions

1) Maybe you need to install all these required packages

> zypper install gcc gcc-c++ make kernel-source [linux-kernel-headers]

2) This is what I've seen after installing the packages.

> rpm -qa | grep kernel
kernel-default-devel-2.6.31.14-0.4.1.i586
kernel-default-2.6.31.5-0.1.1.i586
kernel-source-2.6.31.14-0.4.1.noarch
linux-kernel-headers-2.6.31-3.4.noarch

3) You have to set this env var so that 'VBoxLinuxAdditions-x86.run' can find all the required files.

> export KERN_DIR=/usr/src/linux-2.6.31.14-0.4-obj/i386/default

4) Mount VBOXADDITIONS iso file. VirtualBox menu 'Devices' -> 'Install Guest Additions...'

5) Run 'VBoxLinuxAdditions-x86.run' as root.

> cd /media/VBOXADDITIONS_3.

> ./VBoxLinuxAdditions-x86.run

If you failed to compile VBoxLinuxAdditions, please refer to the log file '/var/log/vboxadd-install.log' to check what really happened.
