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

["Tait Clarridge" <Tait.Clarridge@xxxxxxxxxxxx>]

Argyro,

When you are in the xen-3.2.0 directory type "make linux-2.6-xen-config 
CONFIGMODE=menuconfig"
Then scroll down to the device drivers section and look for RAID + LVM and 
press "y" so a star appears beside them.
You can do a search for the AHCI and USB host sections. There is information on 
how to do so when the configuration menu pops up. Also, make sure you save it.

Then type "make linux-2.6-xen-build" followed by "make linux-2.6-xen-install".

After that you will have to make the ram disk. "mkinitrd 
/boot/initrd.img-2.6.18.8-xen 2.6.18.8-xen -preload=ahci -preload=sd_mod" and 
you can add other modules you think will need to be loaded on boot for the 
system to find the filesystem.

Some of those commands may not work as I haven't done an install in over 2 
weeks. So let me know if they don't and I'll go try myself.

Thanks,
Tait

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.
 
Thanks for your help !!!

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?
 
Thanks

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,
-Tait

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
