Hi Ninny,
thanks for your help.
Here's what I get without using the initrd:
VFS: Cannot open root device "sda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Please let me have your considerations.
Thanks again,
Andrea

Hi,
Could you try to use sda1/sda2 instead of xvda1/2.
ie, disk =
['tap:aio:/xen/mail/fedora.img,sda1,w','tap:aio:/xen/mail/swap1.img,sda2,w']
Also can you comment out the initrd line from DomU grub:
title Fedora Core 3
root (hd0,0)
kernel /boot/vmlinuz-2.6.18-1.2869.fc6xen root=/dev/sda1
# initrd /boot/initrd-2.6.18-1.2869.fc6xenU.img
The error says that kernel could not find /sbin/init , so just try with the
above configuration.
