Subject: [Xen-users] DomU boots but prompts an error related
to modules
Hello all,
I'm installing xen3.1 on an Ubuntu Feisty Fawn 7.04 using the
tarball source. Dom0 works good now! and I can also start
domUs, the problem is that I get this error when I do an xm
create -c sistema.sxp
Couldnt get a file descriptor referring to the console
modprobe: FATAL: Could not load
/lib/modules/2.6.18-xen/modules.dep: No such file or directory
modprobe: FATAL: Could not load
/lib/modules/2.6.18-xen/modules.dep: No such file or directory
Inside DomU you need to do "depmod 2.6.18-xen".
It shows this error about 8 times, but eventually the domU
starts and apparently everything works fine. The point is
that I'm trying to find out why it happens, because I need
this machine to be stable.
I have tried many things to solve this and nothing seems to
work. I compiled my own kernel. Also I decompressed the ram
disk to look for the file that is missing, it's not there so
I put it there manually and made a cpio and gzip, but when I
use the new-initrd.img on the domU it goes the same and if I
try to use my own generated initrd with dom0 doen't boot up
and stalls in the root file system checkup.
This is my sistema.sxp file:
kernel = "/boot/xen/vmlinuz-2.6.18-xen"
ramdisk = "/boot/xen/new-initrd.img"
memory = 128
name = "SistemaPrueba"
vif = ['mac=4E:4F:53:59:53:00' ]
disk= [ 'phy:/dev/vm/sistema,sda1,w',
'phy:/dev/vm/sistema-swap,sda2,w' ]
hostname="SistemaPrueba"
root = "/dev/sda1 ro"
extra = "4"
Yes, I'm using the same xenKernel for the dom0 and the domU.
That should be fine.
The domU is a Feisty debootstrap system with openssh-server
that responds. And it's mounted on a logical volume (which
might be the source of the problem)
Probably not, just simply that you (or anyone else) haven't run the
depmod command to build the "modules.dep" file in the DomU file-system.

Thanks a lot,

I didn't know I had to do a depmod in the domU also, I had made it in
the dom0 but not in the domU. I have had to rsync the files needed
before being able to do it, but then there has been no problem.
The error doesn't prompt anymore, after 2 days trying to solve it,
works!
Thank you so much Mats,
Miguel Araujo
