Ich lass mir noch nen tollen Titel einfallen!

Let’s install Xen under Ubuntu. The installation is very uncomplicated so start with installing the necessary packages.

sudo aptitude install xen-hypervisor xen-utils xen-tools linux-image-xen

After this step run update-grub to make sure that the hypervisor is added to menu.lst. The command will show some output.

Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
Searching for splash image ... none found, skipping ...
Found Xen hypervisor 3.1, kernel: /boot/vmlinuz-2.6.22-14-xen
Found kernel: /boot/vmlinuz-2.6.22-14-server
Found kernel: /boot/memtest86+.bin
Updating /boot/grub/menu.lst ... done


Now it is time to restart the box to boot the hypervisor. There are a lot of different commands to reboot a Linux box. I prefer init 6. When the OS comes up without any problem, everything should be fine. You can approve if the right kernel is loaded by executing uname -a.
