Have you ever wanted to easily clone a virtual machine from a snapshot, and have the clone reflect the source as it existed at that point in time, as opposed to the current status of the source? Jonathan Medd (@jonathanmedd) has a great PowerCLI script that I found yesterday, to do exactly this.
Copy the contents of his script into a new .ps1 file, save it, and then execute the script within a PowerCLI window to add the function to your session. Then run the new function to create your clones. By default it uses the last snapshot in the chain, but you can request a snapshot by name as explained on his site.
