[CentOS] Virtual Machine converted from physical : Kernel Panic at boot .

Hi.

I used VMware Standalone converter 5.5 to convert a CentOS 5.3 machine from
a Physical server to a Virtaul Machine on ESXi 5.1 .  Thus far with every
attempt to convert this machine I get a "Kernel panic"

mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc  failed: No such file or directory
setuproot: error mounting /sys failed: No such file or directory
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!-220000

I have follows the VMware provided solution for this situation but the
results are the same

I have re-installed the CentOS kernel but that didn't make any difference.
I have tried installing disk labels but that didn't make any difference.
I have installed a clean install of 5.3 into a new vm  , I even did a
custom disk configuration to match that created by VMware Converter and
that worked fine with most of the configuration being the same with the
exception that it used disk labels.

I'm at a loss at this point , I'm open to suggestions.

Here are my configs as shown when using a rescue disk and chroot into
/mnt/sysimage
