[Xen-users] Installing Xen 4.0.1 on Ubuntu 10.04

[Marcela Castro León <mcastrol@xxxxxxxxx>]

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.

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.

Hello
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.

Can you ping / ssh into it from another system?

Can you attach a serial console and turn up the xen boot debug
messages (see links below)?

Post your grub.cfg entry.
