I just rebuild the image with the following command and am getting the same
error message.

mkinitcpio -k 2.6.18-xen -g /boot/kernel26xenB.img

/etc/mkinitcpio.conf is:
MODULES="ata_piix ext3"
BINARIES=""
FILES=""
HOOKS="base udev autodetect ide pata scsi sata keymap filesystems"

I also reinstalled the underlying os that I am building on so that the 
filesystem of sda3 is ext3.
Any thoughts on what I am doing wrong?
