HOWTO: Keep and maintain multiple kernel versions

1) Enable multiversion support by uncommenting the following line in /etc/zypp/zypp.conf

# multiversion = provides:multiversion(kernel)

2) Setup automatic deletion of unused kernels in /etc/zypp/zypp.conf

multiversion.kernels = latest,latest-1,oldest

3) Display a list of all kernel packages available for installation

zypper se -s 'kernel*'

4) Install specific kernel version

zypper in kernel-default-2.6.32.10-0.4.1

5) List all kernels installed

zypper se -si 'kernel*'

6) Remove unnecessary kernel package

zypper rm PACKAGENAME-VERSION
