Description Egon Kastelijn 2009-03-20 05:23:28 EDT
Description of problem:
When a Cobbler iso image is generated on the Cobbler server and that iso image is used to boot a virtual guest on KVM or VMWare-ESX then the guest machine does boot, but hangs with the error:
FATAL: Could not load /lib/modules/ No such file or directory

Cobbler buildiso generates an initrd that does not contain the specified directory /lib/modules/
It does contain the directory: /lib/modules/

Cobbler server: Fedora10
Cobbler 'system to be installed': Fedora10 

Version-Release number of selected component (if applicable):
Name        : cobbler
Version     : 1.4.3
Release     : 4.fc10

How reproducible:
See below.

Steps to Reproduce:
1. Install Cobbler on Fedora10
2. Import Fedora10 into Cobbler as a distribution
   cobbler import --path=/var/www/html/linux/fedora/10/i386/ --name=Fedora-10-i386 --available-as=
2. Run the command 'cobbler buildiso --iso=/cobblertest.iso' on the Cobbler serer 
3. Boot the virtual guest from the generated iso image.
Actual results:
The guest machine is unable to start its network interface because it can not load the driver for the network interface.
On the 3rd console (ALT-F3) is the message:
FATAL: Could not load /lib/modules/ No such file or directory

Expected results:
A normal Cobbler-based install over the network.

The only supported VMware mechanism is koan "--virt".

There is no ESX support in koan at this time.  This is something many folks on the list/IRC have talked about adding, but has not been done yet for various implementation reasons.
