I'm trying to convert a physical RHEL 3.9 box to a VM. I used the Enterprise cold boot VMware Converter CD to boot the machine and converted it to a VM on my ESX 3.5 server. That was not a big deal. The problem is that once the VM is created, it won't boot.
I'm getting the following errors:
Hint: ismod errors can be caused by incorrect module parameters including lid IO or IRQ parameters. You may find more information in syslor or the output from dmesg
ERROR: /bin/ismod exited abnormally
VFS: Can not open root device "LABEL=/" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to moutn root fs on 00:00
You will need to boot to a RHEL rescue CD and insert a new SCSI module. Check out this blog post. I use it all the time. Make sure you read the entire post because it deals with different kernel versions.
