Install a virtual machine, then shut down vmware (or that instance, for
GSX/ESX).
Copy its configuration (foo.cfg and virtual disks) elsewhere.
You can now run this copy separately.
You can repeat this as often as you want.
We keep preinstalled Linux and WinXP virtual disk images sitting around
to make "instant" VMware installations.

(Another nifty trick is that you can run an instance in a mode where
changes to its virtual disks are logged by vmware and you can choose to
commit or rollback when you shut down the instance.  I've used this to
make testbeds.)
