Hello everyone, I recently installed Ubuntu 7.10 on a machine to use for playing with Xen using the Ubuntu alternative install CD. The only thing out-of-the-ordinary that I did with the installation has to do with my partitioning. I've taken 2 SATA drives and created 2 raid devices: /dev/md0 is a RAID1 of /dev/sda1 and /dev/sdb1, and /dev/md1 is a RAID0 of /dev/sda2 and /dev/sdb2. /dev/md0 contains / and /dev/md1 is mounted as /media/storage. After the installation, I ran "sudo apt-get install ubuntu-xen-server". Everything went well, but my machine didn't boot up the new Xen kernel. All of the guides involving Debian/Ubuntu and Xen involved using GRUB as a bootloader. In my case, I'm using LILO, so I decided to take a stab in the dark at it. Below is my /etc/lilo.conf file. The good news: /vmlinuz is a symlink to the kernel containing the Xen extensions. The bad news: whenever I run "sudo lilo -v 2", I get this output: bstempi@xen01:/$ sudo lilo -v 2 [sudo] password for bstempi: LILO version 22.8, Copyright (C) 1992-1998 Werner Almesberger Development beyond version 21 Copyright (C) 1999-2006 John Coffman Released 19-Feb-2007, and compiled at 11:30:30 on Aug 10 2007 Running Linux kernel 2.6.22-14-generic on i686 Ubuntu Warning: LBA32 addressing assumed Warning: '/proc/partitions' does not match '/dev' directory structure.

Reminder !! | # | | # | Don't forget to run `lilo' after you make changes to this | # | conffile, `/boot/bootmess.txt' (if you have created it), or | # | install a new kernel.

This is where Lilo installs its boot # block. It can be either a partition, or the raw device, in which # case it installs in the MBR, and will overwrite the current MBR. # boot=/dev/md0 # Specifies the device that should be mounted as root. (`/') # boot=/dev/md0 # Specifies the device that should be mounted as root. (`/') # #root=/dev/mapper/xen01--0-root # This option may be needed for some software RAID installs. # raid-extra-boot=mbr-only # Enable map compaction: # Tries to merge read requests for adjacent sectors into a single # read request. This drastically reduces load time and keeps the # map smaller. Using `compact' is especially recommended when # booting from a floppy disk. It is disabled here by default # because it doesn't always work. # # compact # Installs the specified file as the new boot sector # You have the choice between: text, bmp, and menu # Look in lilo.conf(5) manpage for details # #install=menu # Specifies the location of the map file # map=/boot/map # You can set a password here, and uncomment the `restricted' lines # in the image definitions below to make it so that a password must # be typed to boot anything but a default configuration. If a # command line is given, other than one specified by an `append' # statement in `lilo.conf', the password will be required, but a # standard default boot will not require one. # # This will, for instance, prevent anyone with access to the # console from booting with something like `Linux init=/bin/sh', # and thus becoming `root' without proper authorization. # # Note that if you really need this type of security, you will # likely also want to use `install-mbr' to reconfigure the MBR # program, as well as set up your BIOS to disallow booting from # removable disk or CD-ROM, then put a password on getting into the # BIOS configuration as well. Please RTFM `install-mbr(8)'. # # password=tatercounter2000 # Specifies the number of deciseconds (0.1 seconds) LILO should # wait before booting the first image. # delay=30 # You can put a customized boot message up if you like. If you use # `prompt', and this computer may need to reboot unattended, you # must specify a `timeout', or it will sit there forever waiting # for a keypress. `single-key' goes with the `alias' lines in the # `image' configurations below. eg: You can press `1' to boot # `Linux', `2' to boot `LinuxOLD', if you uncomment the `alias'. # # message=/boot/bootmess.txt # prompt # delay=100 # timeout=100 # Specifies the VGA text mode at boot time.
