Re: [Xen-users] Xen 3.2 is not loading on FC8 - Error: Kernel panic -Attempted to kill init

["Argyro Andreou" <argyro.andreou@xxxxxxxxx>]

So I finally got it to load the xen-kernel by copying ata_generic.ko and libdata.ko from /lib/modules/2.6.23.1-42.fc8/kernel/drivers/ata  to /lib/modules/2.6.18.8-xen/kernel/drivers and adding them into the modules.dep file located in /lib/modules/2.6.18.8-xen in the same manner the exist in the corresponding file in fedora.

 

Thanks for your help

maybe you need to explicitly compile them

make linux-2.6-xen-config CONFIGMODE=menuconfig

select the related drivers

When I try to create my inirtd image the way you said yesterday it says that there is no ata_generic driver for the kernel. So to actually succeed in creating my initrd image I need to ommit the scsi modules which I think it's creating the problem. FC8 has it ata_generic but it's no where to be found in the xen-linux.  How do I get it to compile with the ata drivers? Any ideas???

 

Thanks

I find that most of those in ata directory are moved to scsi directory in xen-linux

I just go into /lib/modules

 

There you will see two directories one for the xen-linux-kernel and one for your standard linux distro in my case FC8. By going into those 2 directories then going into /kernel/drivers I see that the ata driver directory is missing from the xen-linux whereas it's present for FC8

I guess it's close. ata driver may matter!
how do you check the drivers? Maybe I can check the settings on my machine

I did a comparison of the drivers included in the linux-zen kernel and the drivers FC8 has. The only difference is that the linux-xen drivers do not include the ata drivers. Is the linux-kernel downloaded inclomplete? How do I get it to download the ata drivers as well?

 

Thanks

Any ideas how to get it included? Or what I'm doing wrong and it's not compiling the sata controller? LEt me know if you need me to post any info to figure out what's happening.

 

Thanks !!!

I guess it's related with the sata controller driver which should be included in your initrd file.

So then what type of changes would I have to make to the config file to compile the kernel the way you describe? I took a look at it and I it seems to me that the write options are enabled.

I remember that I had to compile all the RAID + LVM section of the kernel config directly into the kernel, and not as modules. As well I had to have each of the USB host sections as modules and the AHCI support built as a module.

Then I compiled my initrd with sd_mod, sg, ahci (I think) to get it to find my logical volumes.

I guess some device driver for your sata driver was not loaded, so the kernel can't find the /dev/root device.
Did you change the .config of linux kernel? By default, it should include most of the drivers.

When installing Fedora Core 8 I didn't do custom partitioning I used the default option. If custom partitioning is need can you please tell me exactly what partitions are needed?

Hi Argyro,
 
Could you take out the "quiet" switch in the Xen kernel boot args and tell us exactly what it says? You might also want to add a "noreboot" in that section so you can write down exactly what it says.
 
Thanks,

Hi all,

I compiled and installed Xen 3.2 source on FC8. Compilation and installation completed with no errors. However when I try to load Xen I get an error: Kernel panic - Attempted to kill init !!!

This is my grub configuration:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=15
splashimage=(hd0,0)/grub/splash.xpm.gz
#hiddenmenu
title Fedora (2.6.23.1-42.fc8)
    root (hd0,0)
    kernel /vmlinuz-2.6.23.1-42.fc8 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
    initrd /initrd-2.6.23.1-42.fc8.img

title Fedora Core 8 + Xen 3.2.0
    root (hd0,0)
    kernel /xen-3.2.1-rc1-pre.gz
    module /vmlinuz-2.6.18.8-xen ro root=/dev/VolGroup00/LogVol00 rhgb quiet
    module /initrd-2.6.18.8-xen.img   

I tried loading Xen without initrd also. But I get the same error.

Please can anyone help me. I've trying to solve this problem since last Friday and I can't see any light at the end of the tunnel


Regards
Argyro
