Re: [Xen-users] PV Lenny 32 bits into 64 bits dom0 - Grub / kernel problem

[Francois Clémence <Francois.clemence@xxxxxxxxxxxx>]

It works !! But maybe this Lenny problem of grub detection should be fix.

Thanks you very much !

I'm aware it will give you errors. But it will still boot - you will need to configure grub manually.

 

Here is a sample grub.conf

 

default=0

timeout=5

hiddenmenu

title Debian 5.0, kernel 2.6.26-1-xen-686

                root (hd0,0)

                kernel /vmlinuz-2.6.26-1-xen-686 ro root=/dev/xvda1

                initrd /initrd.img-2.6.26-1-xen-686

 

Change the root= to whatever your device is.

Thanks for the idea.

But, well still the same problem.

Debootstrop went fine, but apt-get install linux-image-xen-686 gives the same problem :

And update-grub does nothing !

Do you have the same problem/bug  ?

Hi Francois,

 

Use this to do your debootstrap:

 

debootstrap --arch=i386 --include=libc6-xen,firmware-bnx2,grub --components=main,contrib,non-free lenny /mnt/xen http://ftp2.fr.debian.org/debian

 

Then, once complete, chroot /mnt/xen

 

Edit /etc/apt/sources.list to your liking (make sure you add lenny/updates!).

 

mkdir -p /boot/grub

 

apt-get update

 

apt-get install linux-image-xen-686

 

Make sure /boot/grub/menu.lst is configured correctly and you should be good to go.

 

Regards,

Alan

Subject: [Xen-users] PV Lenny 32 bits into 64 bits dom0 - Grub / kernel problem

 

Hello,

I can't solve my problem. I want a 32 bits Lenny domU into a 64 bits Lenny dom0.

I plan to use pygrub for that (xen 3.2.1).

So, I tried to debootstrap a 32 bits domU into a 64 bits dom0.

debootstrap --arch=i386 --include=libc6-xen,firmware-bnx2,linux-image-2.6.26-1-xen-686,linux-modules-xen-686,linux-image-xen-686,grub --components=main,contrib,non-free lenny /mnt/xen http://ftp2.fr.debian.org/debian

But i have this problem at the end :

dpkg: error processing linux-image-2.6.26-1-xen-686 (--configure):
subprocess post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of linux-image-xen-686:
linux-image-xen-686 depends on linux-image-2.6.26-1-xen-686; however:
 Package linux-image-2.6.26-1-xen-686 is not configured yet.
dpkg: error processing linux-image-xen-686 (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:
linux-image-2.6.26-1-xen-686
linux-image-xen-686

I read this article http://ressukka.net/blog/posts/20090217_Xen_domU_upgrades/

So, I update domU.cfg :
bootloader  = '/usr/lib/xen-3.2-1/bin/pygrub'
root        = '/dev/xvda1 ro'
disk        = [
                 'phy:/dev/xen-lvm/386-disk,xvda1,w',
                 'phy:/dev/xen-lvm/386-swap,xvda2,w',
             ]

and domU fstab :
/dev/xvda1 / ext3 defaults 0 1
/dev/xvda2 none swap defaults 0 0
proc /proc proc defaults 0 0

But dpkg --configure -a gives the same dpkg problem !

And update-grub does not generate any files under /boot/grub !!

How to fix that ?

François C.
