Boot failed with linux after conversion (Xen -> ESX)

Hi All,

 

I have been trying to convert my virtual machine running on Xen hypervisor, and the convert was success. However, when I tried to boot the server at the target ESX, it failed to do it. The symptom is that

 

- Redhat 6.x: the screen did not show anything and the scroll lock key was on and off (I heard this is a kernel panic).

- CentOS 6.x: the last message shown on the screen was "Probing EDD (edd=off to disable)... ok".. I assume that EDD probing was success.. but after that, the kernel panics.

 

The source virtual machine partition below looks very normal to me. There are no special kernel arguments passed.

I have no clue at all why this happens... if someone can help out, it would be great!!!
