# Version 2.4 (27-03-2017) <# .Synopsis This module lets you roll out your lab environment automatically. This is the second step: creating a Lab VM's. .DESCRIPTION This module lets you roll out your lab environment automatically as described in our blogs (www.365dude.nl and www.svenvanrijen.nl). This is the second step: creating Lab VM's. First step: creating a NATSwitch (New-NATSwitch). New-LabVM generates a new VM in the lab environment. IPAddress is a mandatory parameter and must be in the "172.16.10.10/24" notation. Please use the same address space as used when creating the NATSwitch. The specification of a Gateway is optional. If DNS-server is not specified, the default will be used. (172.16.10.1) The specification of a DNS-server is optional. If DNS-server is not specified, the default will be used.
