Re: [Xen-users] Fedora Core 5 boot problems
Please include the list on your replies, I'm out of town at the moment
so you'll probably get quicker responses from others on the list.
You need to run e.g.:
depmod -a 2.6.16-xen
(This is the same procedure you would use to install any new Kernel, Xen
or otherwise.)

Hi James
I tried this and got the error message ..
No dep file found for kernel
I then tried copying the modules.dep file from the stock fc5 kernel and tried mkinitrd again. It went through and created the initrd.
I then tried booting with the new initrd .. it works but a number of modules ..
espescially network interfaces (eth0, eth1) do not load and produce errors.
Any idea where I need to get the modules.dep file from ? Or am I missing
something else ?
Cheers
Srini

If you install from tarball you need to create this yourself, e.g.:
/sbin/mkinitrd /boot/initrd-2.6.16-xen.img 2.6.16-xen
(and update grub)
The install.sh script does not do this automagically because initrd
generation is distribution-specific.

Thanks for a prompt response ..
I could not find any initrd for the Xen 3.o in my /boot ..
Do I need to do a mkinitrd ? Any hints will help

You're using the kernel from the binary tarball and the initrd
from the FC5 non-Xen kernel. To a first approximation kernel
version and modules (in the initrd) must match.

Hi
I had Xen 2.x running peacefully on FC4 .. sigh.
Yesterday I upgraded to FC5 and also downloaded and installed
the new Xen version 3.x from xensource.com .. I installed via
the precompiled tarball.
My grub entries loook like this:
title Xen 3.0 (Fedora/XenLinux 2.6)
root (hd0,4)
kernel /xen.gz dom0_mem=260000
module /vmlinuz-2.6-xen root=/dev/sda6 ro console=tty0
module /initrd-2.6.15-1.2054_FC5.img
boot
My /etc/fstab looks like this:
/dev/sda6 / ext3
defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
/dev/sda7 swap swap defaults 0 0
...
Fedora is installed on a SATA hard disk, partition /dev/sda6
Xen boots and then soon after reports a kernel panic and after
a few seconds reboots .. I was unable to get the messages
before the last screen but managed to capture the last messages
on screen .. reported below.
...
Loading jbd.ko module
jbd: disagrees about version of symbol struct_module
insmod: error inserting /lib/jbd.ko: -1 invalid module format
Loading ext3.ko module
ext3: disagrees about version of symbol struct_module
insmod: error inserting /lib/ext3.ko: -1 invalid module format
Creating root device
Mounting root filesystem
mount: could not find filesystem '/dev/root'
Setting up other filesystems
Setting up new root fs
setuproot: moving /dev failed: No such file or directory
no fstab.sys, mounting internal defaults
setuproot: error mounting /proc: no such file or directory
setuproot: error mounting /sys: no such file or directory
Switching to new root and running init
unmounting old /dev
unmounting old /proc
unmounting old /sys
switchroot: mount failed: no such file or directory
Kernel panic - not syncing: Attempted to kill Init:
And then the system quickly reboots.
Any help to fix this is appreciated.

Srini
