Hello:
I've solved the boot problem but now i've another error.
The xen can´t mount the device, so, after show me the errors, its stop at "initramfs" prompt.
This is the error that shows:
mount: mounting none on /dev failed.
no such device
begin loading essencial drivers
done
Begin running /scripts/init_premount
done
begin
mounting root file system
running scrip/local_top ...
done
Gave up waiting for root device . Common problems
- boot args (cat /proc/cmdline
- check root delay ...
- check root ...
-Missing modules /cat /proc/modules (ls/deb
Alert! does not exist Dropping to a shell
(initrams)
I've recompiled selecting the option of "ext4" (make menuconfig), because i'm using this kind of fs, but i've got the same error.
Someone cant say me what woulb be wrong?
Thank you very much,
This is that Boris asked me before and the grub.cfg

Sounds like you're missing a driver for your root block device. Not sure what to tell you to add, perhaps one of the piix pata/sata devices?
Or, perhaps you're missing the xen_blkfront driver.
Might be that you're just missing the driver from your initrd.
After you're at the initramfs prompt, do you see any /dev/sd* or /dev//hd* devices?

Date: Tuesday, November 2, 2010, 10:57 AMHello Boris: I did it, but I've got the same result. thank you very much. Marcela 2010/11/2 Boris Derzhavets <bderzhavets@xxxxxxxxx>
menuentry "Xen 4.0.1 / Ubuntu 10.04 kernel 2.6.32.24" {
recordfail
insmod ext2
set root='(hd0,5)'
multiboot (hd0,5)/boot/xen-4.0.1.gz dom0_mem=1024M loglvl=all guest_loglvl=all sync_console
module (hd0,5)/boot/vmlinuz-2.6.32-24 root=/dev/sda5 ro nomodeset
module (hd0,5)/boot/initrd.img-2.6.32-24
}
If this is your config, i would change it :-
menuentry "Xen 4.0.1 / Ubuntu 10.04 kernel 2.6.32.24" {
recordfail
insmod ext2
set root='(hd0,5)'
multiboot (hd0,5)/boot/xen-4.0.1.gz dom0_mem=1024M loglvl=all guest_loglvl=all
module (hd0,5)/boot/vmlinuz-2.6.32-24 root=/dev/sda5 ro console=tty0
module (hd0,5)/boot/initrd.img-2.6.32-24
}
Boris.

Date: Tuesday, November 2, 2010, 10:10 AMHello This is the grub.cfg. The system hangs-up when try to boot with dom0 kernel, so, I can't ping any host. The last message that show is
"(XEN) dom0 kernel not specified. Check bootloader configuration. "
I'm trying to configure the serial console and turn up the boot, and i'll send you more infomation if I get it, because is still hanging up. Thanks in advance. Marcela
