    We compiled xen-3.4.2 (2.6.18.8-xen).
    The grub entry, and the partition information to boot from /dev/sda1 is as follows.


    1. /boot/grub/menu.lst:

    title Xen
    uuid 30ec981c-187e-4488-ae98-fe54ad13a77b
    kernel /boot/xen-3.4.gz console=vga
    module /boot/vmlinuz-2.6.18.8-xen root=UUID=30ec981c-187e-4488-ae98-fe54ad13a77b ro console=tty0 rootdelay=90
    module /boot/initrd-2.6.18.8-xen.img


    2. fdisk:

    Disk /dev/sda: 122.9 GB, 122942324736 bytes
    255 heads, 63 sectors/track, 14946 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0x000e4ad4

    Device Boot Start End Blocks Id System
    /dev/sda1 * 1 1376 11052688+ 83 Linux
    /dev/sda2 14335 14946 4915890 5 Extended
    /dev/sda3 1377 11587 82019857+ 83 Linux
    /dev/sda4 11588 14334 22065277+ 7 HPFS/NTFS
    /dev/sda5 14335 14946 4915858+ 82 Linux swap / Solaris

    Partition table entries are not in disk order


    3. /etc/fstab:

    # /dev/sda1
    UUID=30ec981c-187e-4488-ae98-fe54ad13a77b / ext3 relatime,errors=remount-ro 0 1
    # /dev/sda5
    UUID=3896c65c-3908-412d-8d3d-e5593a6e674e none swap sw 0 0


    4. /dev/disk/by-uuid/:

    total 0
    lrwxrwxrwx 1 root root 10 2010-03-01 14:43 1385D7DA6D83F67F -> ../../sda4
    lrwxrwxrwx 1 root root 10 2010-03-01 14:43 30ec981c-187e-4488-ae98-fe54ad13a77b -> ../../sda1
    lrwxrwxrwx 1 root root 10 2010-03-01 14:43 3896c65c-3908-412d-8d3d-e5593a6e674e -> ../../sda5
    lrwxrwxrwx 1 root root 10 2010-03-01 14:43 6c4a7894-1a6a-46b7-b020-7a3cfa859283 -> ../../sda3


    When we boot the new Xen kernel, we get the messsage:
    ALERT! /dev/disk/.......does not exist. Dropping to a shell!

    We tried several other settings for "root=" in the menu.lst such as
    root=/dev/sda1, etc.
    But none of them worked. We kept getting the same error message "..... does not exist".

    Can somebody figure out why does this happen? Thanks a lot in advance!

    Which distribution do you use? What tutorial (URL) did you use to set up the system?

    I use Ubuntu 8.10 (Intrepid Ibex). I just follow the README file and official Xen user tutorial from http://www.xen.org/support/documentation.html

    Is it possibly a hardware (eg. hard drive) compatibility problem?
