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 http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1002402 http://blog.edgoad.com/2010/03/vmware-no-volume-groups-found.html 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 [root at localhost /]# cat /boot/grub/grub.conf # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.
