23.6.2 Verifying That the GRUB Boot Loader
When the Xen software packages are installed, the GRUB boot loader is automatically
updated to present the VM Server as a boot option. The GRUB boot loader configuration
file is usually saved to /boot/grub/menu.lst.
You might want to compare your GRUB boot loader configuration file with the sample
below to confirm that it was updated to correctly boot VM Server. The first example
shows a typical GRUB boot loader file updated to load the Xen software. The second
file shows a GRUB boot loader file that loads a PAE-enabled kernel, which allows 32-
bit computers to access memory over 4 GB.
Sample GRUB Boot Loader File (Typical)
title XEN
root (hd0,5)
kernel /boot/xen.gz hype_parameters
module /boot/vmlinuz-xen kernel_parameters
module /boot/initrd-xen
Sample GRUB Boot Loader File (PAE)
title XEN
root (hd0,5)
kernel /boot/xen-pae.gz hype_parameters
module /boot/vmlinuz-xenpae kernel_parameters
module /boot/initrd-xenpae
The title line specifies the name of the GRUB module. Do not change this line be-
cause YaST looks for the word Xen to verify that packages are installed.
The root line specifies which partition holds the boot partition and /boot directory.
Replace (hd0,5) with the correct partition. For example, if hda1 holds the /boot directory,
the entry would be (hd0,0).
The kernel line specifies the directory and filename of the hypervisor software. Re-
place hype_parameters with the parameters to pass to the hypervisor. A common
parameter is dom0_mem=amount_of_memory, which specifies how much memory
to allocate to the VM Server. The amount of memory is specified in KB, or you can
specify the units, for example 128M. If the amount is not specified, the VM Server
