May Kubuntu 8.04.1  be replaced by Ubuntu 8.04.1 ?
Intrepid Xen 3.3 Hypervisor may be just back ported to Hardy Dom0 via Synaptic Manager, keeping native xenified kernel in place. Would it be acceptable ?

Hello All,

I am facing problems in booting up Xen on Kubuntu 8.04.1

Booting crashes giving message "ALERT! does not exist. Dropping to a shell !"

Last couple of lines are,

sd 4:0:0:0: Attached scsi removable disk sdb
sd 4:0:0:0: Attached scsi generic sg1 type 0
         Check root=bootarg cat /proc/cmdline
         or missing modules, devices: cat /proc/modules ls /dev
ALERT! does not exist. Dropping to a shell !
BusyBox v1.1.3 (Debian 1:1.1.3-5ubuntu12) Built-in shell (ash)

I followed the procedure given on http://lists.xensource.com/archives/html/xen-users/2008-01/msg00700.html to install Xen

1. Created a "xen/build" directory on Desktop
2. Extracted xen-3.3.0.tar.gz in this folder
3. hg clone http://xenbits.xensource.com/linux-2.6.18-xen.hg (At the same level as that of xen-3.3.0)
4. cd xen-3.3.0
5. make linux-2.6-xen-config CONFIGMODE=menuconfig
6. cp /boot/config-2.6.18-xen build-linux-2.6.18-xen_x86_64/.config
7. make linux-2.6-xen-build
8. make install
9. cd /boot
10. mkinitramfs -o initramfs.img-2.6.18-xen 2.6.18-xen
11. added a grub entry for xen in menu.lst
# This entry has been manually added for xen
title        Xen 3.3 / XenLinux 2.6
root        ()/ubuntu/disks
kernel        /boot/xen-3.3.0.gz root=UUID=C4A2BD12A2BD09C6 loop=/ubuntu/disks/root.disk ro
module        /boot/vmlinuz-2.6.18-xen
module        /boot/initramfs.img-2.6.18-xen
12. reboot

And then I choose Xen 3.3 / XenLinux 2.6 option during booting. It starts booting and ultimately crashes throwing the message "ALERT! does not exist. Dropping to a shell !".

If I execute cat /proc/cmdline, it gives nothing.

If I execute cat /proc/modules or ls /dev, it lists some devices. (I can give this list if you think that is important.)

I have attached the menu.lst with this mail for reference.

Can anybody help me solving this problem? It is very important.

Thanks in advance.
