Well first of all the .localized extension is hidden by default and one would not normally see it in Finder although in a Terminal one would. Secondly the .localized extension may not exist on the Virtual Machines folder under Tiger IIRC.
Virtual Machines created natively in Fusion have a .vmwarevm extension (hidden by default) on the folder the files that comprise the Virtual Machine are stored and this makes it a Document Package so searching in Spotlight for vmwarevm is one way to find the Virtual Machine Package.
Another way to search the hard drive is to use the find command in a Terminal looking for either *.vmwarevm or *.vmx and the latter is especially if you have any Virtual Machines that are not in a Package. Using Terminal the command would be as follows.
sudo find / -name *.vmwarevm
Or
sudo find / -name *.vmx
This type of search can take a while a since it searches the entire hard drive starting in the root of the drive.

If you do not have a Virtual Machines folder within the Documents folder you might have a Boot Camp partition Virtual Machine and that is located at the following location.
"/Users/$/Library/Application Support/VMware Fusion/Virtual Machines/Boot Camp"
