• Select a specific hypervisor
• Pass additional parameters to the hypervisor (see
/usr/share/doc/packages/
xen/pdf/user.pdf
section “Xen Boot Options” after installing the package
xen-doc-pdf
).
You can customize your virtualization environment by editing the
/boot/grub/
menu.lst
file.
If the Xen option does not appear on the GRUB boot menu, you can compare your up-
dated GRUB boot loader file with the examples below to confirm that it was updated
correctly.
The first example shows a typical GRUB boot loader file updated to load the kernel
that supports virtualization software. The second example shows a GRUB boot loader
file that loads the PAE-enabled virtualization kernel.
Example 5.1 Xen Section in the menu.lst File (Typical)
title XEN
root (hd0,5)
kernel /boot/xen.gz hyper_parameters
module /boot/vmlinuz-xen kernel_parameters
module /boot/initrd-xen
Example 5.2 Xen Section in the menu.lst File (PAE)
title XEN
root (hd0,5)
kernel /boot/xen-pae.gz hyper_parameters
module /boot/vmlinuz-xenpae kernel_parameters
module /boot/initrd-xenpae
The
title
line defines sections in the boot loader file. Do not change this line, because
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 the drive designated as
hda1
holds the
/boot
directory, the entry would be
hd0,0
.
The
kernel
line specifies the directory and filename of the hypervisor. Replace
hyper_parameters
with the parameters to pass to the hypervisor. A common pa-
rameter is
dom0_mem=<amount_of_memory>
, which specifies how much memory
