The errors you're receiving on depmod/lsmod look like you're using the wrong version of the module tools on the kernel.  It looks like you're trying to use the 2.6 module tools (module-init-tools, I think??) on a 2.4 kernel (usually using the 2.4 tools on 2.6 produces Seg Faults).  Try making sure that your kernel, modules, and module utilities match.

Hi all,

I'm new to this list and would like to tip my hat to the Xen development
team you guys have made me look good...!

Here's the scenario :

I'm building a little demo server for a local IT shop to demonstrate how
linux can be use for SME's

Dom0 is installed and working on Fedora Core 4 running
2.6.11-1.1369_FC4xen0.

What I would like to do is install 4 VM's on smeserver from contribs.org
one openfiler from openfiler.org and one fedoracore3 + qemu + windows XP
and one Fedoracore 4.

The last two I'm done before and I know it works, but openfiler and
smeserver run on top of centos 3 with a 2.4 kernel. which is not a big
deal for most configuration, but openfiler needs at least one LVM
partition to create shares on.

so here's what I did

1- I've created 3 disk image.

OpenFiler1.2-1.img ------->sda1
OpenFiler1.2-1.swap.img --------->sda2
OpenFiler1.2-1.stg.img ---------->sda3

2- fdisk /dev/sda3

Disk /dev/sda3: 3221 MB, 3221225472 bytes
255 heads, 63 sectors/track, 391 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot    Start       End    Blocks   Id  System
/dev/sda3p1             1       391   3140676   8e  Linux LVM

3 - pvcreate /dev/sda3
pvcreate -- ERROR: "/etc/lvmtab" doesn't exist or is unreadable; you may
need to run vgscan

4-  vgscan
vgscan -- LVM driver/module not loaded?

5-  lsmod
Module                  Size  Used by    Not tainted
lsmod: QM_MODULES: Function not implemented

6- depmod -ae
depmod: QM_MODULES: Function not implemented


I've copied all the module from /lib/modules/2.6.11-1.1369_FC4xenU to
<disk image mount>/lib/modules/2.6.11-1.1369_FC4xenU

Now I'm stuck and running out of ideas ?
please help ASAP

H
