Did you choose to reconfigure the disk controllers when you ran the convert. I have seen this where the host system had a proprietary raid controller for its local disks and converter was told to leave them as source.

Actually that article refers to fixing a ESX host SC boot problem, not a particular VM boot problem.

nithinprabhakar: I used vmware converter 4.0.1 with a cold clone version of redhat is release 7.1sbe

bgoering: It did not ask me during the converter process using cold clone to change the controller type. It is setup as a buslogic SCSI controller.

Did it add your boot volume as SCSI 0:0? Did the original machine have some diagnostic partition that also got converted? If so you may need to change the scsi addressing - and you likely will not need the diagnostic partition.

What is the physical machine running off of - SCSI?

You may want to look at the lilo.conf or grub.conf files on the virtual image that is not booting.  You can do this by using a redhat/centos rescue CD or a knoppix cd and boot the broken virtual machine off of it, and through the vmware console looking at the VM's boot files.  

Here is a VMware KB that has some more information:

Hi

I made 2 thinks on my RH migration, and also had a Kernal panic

Before any changes, just create a Snapshot to the Initial State

First change the SCSI controller to LSI Logic. Changing this the RH CD1 will recognize your RH installed

After Boot the VM with the RH CD1 and choose to Linux rescue

Then at the prompt enter chroot /mnt/sysimage
Move to boot partition – cd /boot
Check partition contents by using the ls, if you see your /boot content then rebuild the ramdisk installer

Then: mkinitrd –v –f initrdxxxx.img xxxxx the last xxx are your Kernel version

Same times mkinitrd can be dificult to recreate, type the right initrd img and the right Kernel Version

This i think will put your RH bootable

Hope this can help
