-kernel-xen.sh: This script builds the Linux Kernel for a Xen Hypervisor.
-
-The configuration files included here are based on generic Slackware configs.
-For 32bit systems, SMP based config was used. You can run "make menuconfig"
-before compiling a Xen kernel by passing the "MENUCONFIG=yes" to the script.
-
-Originaly, booting a Xen kernel with LILO bootloader is not supported, so GRUB
-has to be used. Since some of us still preffer LILO over GRUB, there is a way
-to accomplish this with mbootpack. Basicaly mbootpack takes Linux kernel, initrd
-and Xen VMM, and packages them up as a single file that looks like a bzImage
-Linux kernel. To select how kernel is packed use "BOOTLOADER=" variable. Valid
-options are "lilo" and "grub".
-
-Since generic kernel requires an initrd image, there are aditional variables that
-can be used, such as ROOTMOD (list of root filesystem modules), ROOTFS (name of a
-module to use) and ROOTDEV (name of root filesystem device).
-
-After a new kernel image is created, add something like the folowing to lilo.conf:
-
-image = /boot/vmlinuz-xen
- root = /dev/sda1
- label = XenLinux
- append="dom0_mem=512M -- nomodeset"
- read-only
-
-Note: everything before "--" is passed to Xen, and everything after "--" is
-passed to the Linux kernel.
-
-If for some reason LILO is not good enough, you can always use GRUB.
-GRUB may be installed from Slackware's extra repository. The GRUB package
-is not available from the Slackware x86_64 distribution, but the source
-and a SlackBuild may be found in its extra/source repository.
-
-grubconfig that comes with Slackware's GRUB package may give a starting point
-to configure GRUB. Moreover, the Xen User Manual and its README file installed
-with the Xen package include details on which parameters to include in the GRUB
-configuration file. For example, include these lines in /boot/grub/menu.lst:
-
-title Slackware XenLinux 14.0
- root (hd0,0)
- kernel /boot/xen.gz dom0_mem=524288 console=vga
- module /boot/vmlinuz-xen root=/dev/sda1 ro console=tty0 nomodeset
- module /boot/initrd-xen.gz
-
-Note that dom0_mem parameter is critical for a 32bit install.
-
-If your dom0 kernel crashes or freezes at boot, either with an automatic reboot
-or with the blank screen, here are some things to try:
-- Specify an out of range number to "fbcon" to disable framebuffer altogether,
- for an example append fbcon=map:9 to the Linux kernel.
- (To see a list of available devices in your system: cat /proc/fb)
-- Blacklist framebuffer module from loading. This one requires a bit of
- digging arround in dmesg/lsmod to find out wich module is in use.
-- Disable framebuffer devices by setting CONFIG_FB=n in kernel config.
-- Try another VGA card (sorry).
