Xen 4.0.1 + Centos 5.5 DOM0 kernel panic on boot
Hey all.
It's been several years since I used Xen "from scratch." Yesterday I built Xen on a Sun X4270 M2 (I only mention the hardware because it's a 100% Xen certified system) and haven't been able to get the dom0 to boot yet. Correction: I'm using Xen 4.1.1, not 4.0.1.
The first error reads, "cannot load bzImage v2.04 at least v2.08 is required."
Then I see "Panic on cpu0: Could not set up DOM0 guest OS."
Here are the lines in my grub.conf pertaining to my Xen:
title Xen4.0.1
root (hd0,0)
kernel /xen.gz dom0_mem=4096 loglvl=all guestloglvl=all
module /vmlinuz-2.6.18-194.el5 root=/dev/sda1 nomodeset console=tty0 console=ttyS0,115200n8
module /2.6.18-194.el5-xen.img
The first of these lines beginning with "module" is where I think the problem might be. In all the how-tos I have seen, this line looks like,
module /vmlinuz-2.6.18-194.el5xen root=/dev/sda1 nomodeset
but I can't find a file on my system named, "vmlinuz-2.6.18-194.el5xen".
The Xen install script moved all the xen* files into /boot but I had to generate the initrd file (which perhaps I do not need.) I did a "make world" without any problems and the "make install" reported no errors either.
Here's what my /boot dir looks like:
[root@mmpqplovm000001 boot]# ls
2.6.18-194.el5-xen.img symvers-2.6.18-194.el5.gz xen-4.1.gz
config-2.6.18-194.el5 System.map-2.6.18-194.el5 xen-4.gz
grub vmlinuz-2.6.18-194.el5 xen.gz
initrd-2.6.18-194.el5.img xen-syms-4.1.1 xen-4.1.1.gz
lost+found
Any hints will be appreciated.
Thanks.
