 This contains the bare minimum options to be configured for the VM to be provisioned.  The entire code block provisions a Windows and a Linux VM, but feel free to delete one or the other and corresponding outputs. The outputs are also not necessary to provision, but included to make it convenient to know the address to connect to the VMs after provisioning completes.
