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/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

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

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!
