-kernel-xen.sh: Xen dom0 kernel using rebased OpenSUSE xen-patches.
-
-This script patches and builds the Linux Kernel for the Xen Hypervisor.
-
-To run this scipt you will need the Xen kernel patches in this directory.
-The patches may be downloaded from:
-http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.34-6.tar.bz2
-(md5sum: afb08178200fa34fd24c4d9d03174102)
-
-Note on kernel: You will need to get kernel version 2.6.34.7 because patches
-based on Slackware stock kernel tree (2.6.33.4) do not work as expected.
-Anyway, you can get it from:
-http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.34.7.tar.bz2
-(md5sum: 8964e26120e84844998a673464a980ea)
-
-The included configuration files are based on Slackware's kernel. For
-Slackware32, the SMP kernels were used as the non-smp kernels would not compile
-with the Xen patches. For the Xen-specific parameters, the default options were
-used as much as possible. You may run "make menuconfig" before compiling the
-Xen kernel by passing the "MENUCONFIG=yes" to the scipt.
-
-Another variable worth mentioning here is "BOOTLOADER=", you can use it to
-select how kernel is packed. Valid options are "lilo" and "grub".
-
-By default, the huge kernel is chosen, but you may opt for the generic kernel
-by passing the "KERNEL=generic" variable to the script. In this case, you
-will need to make an ad-hoc initrd after installing this package.
-For example:
-
-depmod 2.6.34.7-xen
-mkinitrd -c -k 2.6.34.7-xen -f ext4 -r /dev/sda1 -m ext4 -o /boot/initrd-xen.gz
-
-For details on initrd, read /boot/README.initrd, run
-/usr/share/mkinitrd/mkinitrd_command_generator.sh for hints and read the Xen
-User Manual and the README file that comes with the Xen package.
-
-Since booting Xen kernel with LILO is not supported by default we have to
-either use GRUB, or mbootpack to create a LILO compatible kernel.
-
-This is an example how to do it with LILO, mbootpack and initrd:
-
-cd /boot
-gzip -d -c /boot/xen-4.0.1.gz > /boot/xen-4.0.1
-gzip -d -c /boot/initrd-xen.gz > /boot/initrd-xen
-mbootpack -o /boot/vmlinuz-2.6.34.7-xen -m /usr/src/linux-2.6.34.7-xen/vmlinux \
- -m /boot/initrd-xen /boot/xen-4.0.1
-
-After 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=256M -- 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 13.1
- root (hd0,0)
- kernel /boot/xen.gz dom0_mem=262144 console=vga
- module /boot/vmlinuz-xen root=/dev/sda1 ro console=tty0 nomodeset
- module /boot/initrd-xen.gz
-
-Notes on bootloader:
- A dom0_mem parameter is critical for Slackware32.
- You only need the initrd module if you install the generic kernel.
-
-Aditional notes on framebuffer:
- If your dom0 kernel gets stuck on boot with a blinking cursor on the screen,
- and you have an old VGA card, don't panic, there is a way arround it!
- Easiest method is to boot from non-xen kernel, and blacklist a framebuffer
- module from ever loading. Another option would be to replace VGA card with
- a newer one, or remove module in the next kernel build.
