Panic on CPU0 : Unable to boot with Xen 4.1 on Fedora 16, manual grub2 config.
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. -- Ranjith Krishnan _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

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 ?
