Re: [Xen-users] Panic on CPU0 : Unable to boot with Xen 4.1 on Fedora 16, manual grub2 config.

[Ranjith Krishnan <pkranjithpk@xxxxxxxxx>]

Hello,

Could anyone help me out with this please. I am at a loss as to what went wrong. 

Or should I post this in Xen-devel mailing list ?

Thanks,

Ranjith

Hello, 

Newbie here. So please be patient. If you need any extra information please ask, and I will try to provide.

My intention is to study xen source and hopefully make some contributions to it. So I tried to compile Xen 4.1 from source and start using it.

My environment details:

2.0 GHz 32 bit CPU, 2GB RAM with XP and Ubuntu Wubi install. ( Ubuntu installed as an application within XP, can dual boot)

Trying to install Xen on external USB Hard disk (500 GB) : Installed Fedora 16 on this. Can boot and use Fedora 16 just fine from this.

I found these tutorials after searching and used them.

1. http://wiki.xen.org/wiki/Fedora_13_Xen_4_Tutorial

Used a partition scheme very similar to one mentioned in above tutorial. Also disabled selinux.

2. Found a second tutorial for building xen from source:

http://wiki.xen.org/wiki/Compiling_Xen

3. I only complied and installed Xen, not linux kernel ( because wiki says Fedora16 kernel is a valid Xen Dom0 Kernel ) according to http://wiki.xen.org/wiki/Fedora_16_Dom0

After I installed Xen, confirmed that under /boot I have xen.gz, and the folder /etc/xen exists.

I modified my grub2.cfg file by looking at a sample grub2 configuration mentioned at http://old-list-archives.xen.org/archives/html/xen-changelog/2011-10/msg00151.html

Now when I boot with Xen 4.1, it gives me a Kernel panic and fails to load the dom0 kernel. Exact error message is

'elf_xen_note_check: ERROR: Will only load images built for the generic loader or Linux images')

PANIC on CPU0: 


Could not setup DOM0 guest OS 

I am also attaching my grub2.cfg file. Please take a look.
