Are there any tools to diff two VMWARE Windows XP images

You should also have the tools loaded for ease of guest shutdown and power management. Being able to shut the guest operating system down from the Vcenter server or infrastructure client is handy.

I would suggest trying bind mounts (like /Database already is) rather than the unlink/relink games that page has you play.

Try something like /Database/rootfs/lib/modules /lib/modules none rw,bind 0 0 in /etc/fstab for /lib/modules.

Alternatively, I assume your problem replacing the /lib symlink was that commands started to fail immediately after the /lib symlink was removed. That's likely because the replacement was not atomic. You might have better luck with ln -sfT /Database/rootfs/lib /lib as that should be more atomic if not, in fact, actually atomic (I don't know offhand).
