I use this script to deploy one or more identical servers in Hyper-V
. The script handles both the use of a Golden Image template .VHDX file, or a clean installation using an ISO install image and will provide you with a question by question gathering of the most common installation parameters
.
Prerequisites:
- Windows Server 2012 release candidate or above
- Powershell 3.0
- Hyper-V role installed on the server
- Hyper-V Powershell module installed on the server
- A template VHDX file for each operating system you’d like to be able to deploy
- ISO-files for each operating system you’d like to be able to deploy
