Windows Server 2008 and SYSPREP in a VMware enviroment

Filed under: Tools,Virtual Center,vSphere (ESX),White Papers — Tags: , , , , , , , , , — A. Mikkelsen @ 19:52 pm

After we have allowed Windows 2008 Servers in our VMware VI enviroment, we been having problems sysprepping Windows 2008 Server.
So here is a quick guide to sysprep a Windows 2008 server in a VMware VI enviroment.
(Use this workaround until VMware VI allows you run sysprep against a WIN2008 Server)

  1. Change the source or templates Guest Operating Systemsetting to “Vista (32 bit)” or “Vista (64 bit)” depending on the installation of the Windows 2008 server installation.
  2. Clone the VM or template and you are now able to customize your Win2008 server with sysprep.
  3. After the cloning is done Power On the new VM and let the customization complete.
  4. Shutdown the VM and change the Guest Operating Systemsetting back to “Windows Server 2008 (32/64 bit)”

The reason the above workaround works is that Vista and Server 2008 has sysprep build into the OS and the sysprep in both OS’s and are based on the same technology.

Graph history on your ESX enviroments development

2 years ago a VMUG user in Denmark created a Ubuntu VM that could graficily could show the develeoment of the amount of VM’s in a Cluster.

Unfurtionally someone stole my labtop and the VM :-).

So I had to create a new. And of cause it’s based on PowerShell ;-).

The webpages shows the following information

  • Amount of VM’s in each Cluster
  • Amount of Hosts in each Cluster
  • The size of each Datastore and the amount of free disk space

Get the source code in the Download section under Vi Toolkit for Windows
