[Xen-users] Unable to boot patched 2.6.34.6 kernel (bzImage not being ge
Hi,
I'm trying to run Xen 4.0.1 on top of Slackware 13.1 32bits. I managed to install grub on it, managed to install Xen but I'm not able to boot with a xenified 2.6.34.6 kernel for Dom0.
With Xen enable (CONFIG_X86_XEN=y), bzImage is not created, vmlinuz created not able to boot. If I disable Xen, everything is fine.
This is the vmlinuz generated with Xen enable:
root@slacktest1:/usr/src/linux-2.6.34.6# file arch/x86/boot/vmlinuz arch/x86/boot/vmlinuz: gzip compressed data, from Unix, last modified: Tue Nov 16 12:48:20 2010, max compression
root@slacktest1:/usr/src/linux-2.6.34.6# find . -name arch/x86/boot/bzImage root@slacktest1:/usr/src/linux-2.6.34.6#
I'm not able to boot from this patched kernel, even with an initrd image.
Just FYI, this is a bzImage that actually works:
root@slacktest1:/usr/src/linux# file arch/x86/boot/bzImage arch/x86/boot/bzImage: Linux kernel x86 boot executable bzImage, version 2.6.33.4-smp (root@slacktest1) , RO-rootFS, swap_dev 0x2, Normal VGA root@slacktest1:/usr/src/linux# find . -name bzImage
./arch/i386/boot/bzImage ./arch/x86/boot/bzImage root@slacktest1:/usr/src/linux#
This is menu.lst Xen related:
# Linux bootable partition config begins title Linux-Xen on (/dev/sda1) root (hd0,0)
kernel /xen.gz module /vmlinuz-2.6.34.6-xen-20101116a ro root=/dev/rootvg/root rd_LVM_LV=rootvg/root vga=788 module /initrd8.img # Linux bootable partition config ends
Even if I try to boot from xenified kernel without /xen.gz module, this is the grub error I got:
Error 13: Invalid or unsupported executable format
root (hd0,0) kernel /vmlinuz-2.6.34.6-xen-20101116a ro root=/dev/rootvg/root rd_LVM_LV=rootvg/root vga=788 initrd /initrd8.img
I also noticed that if I enable Xen, Kernel compression mode (-> General setup) I have only one choice, Gzip. With Xen disabled, these are my choices:
Gzip Bzip2 LZMA LZO
Not sure if this is related or not.
Patches are from Andrew's (http://code.google.com/p/gentoo-xen-kernel/downloads/list) Kernel 2.6.34.6 is vanilla.
Any light on this will be highly appreciated.
Thanks and regards.
Chris
