For testing purposes, whilst developing a zeroconf daemon I needed to be able to quickly create some VMs and register them on vSphere. The process of opening infrastructure client and running through the wizard etc. or other methods of creating virtual machines was just too slow. After a bit of searching around and looking at, it became apparent that VMware don’t support creating virtual machines from their CLI toolset.

I found script from 2006 that uses commands that don’t even exist anymore, but with a bit of of tweaking will happily create test virtual machines.
