vCloud Automation Center – vCAC 5.1 – Automated Installation Of Windows Guest Agent

In this article I’m gong to walk through automating the installation of the Windows Guest Agent. There are advantages to automating the guest agent installation. One advantage is instead of pre-installing it in your template you can script the install using the “Run Once” capability exposed through the vCenter Customization Specification.
 
Included in the vCAC installation package is a zip file named DCAC-GuestAgent2010Zip.zip. This has all the exploded files that are used within the Windows Guest Agent Installer. These are the files we will be utilizing to manually install the service.

Preparing the files for Installation

1. First thing we need to do is extract the zip file so we can access the files within it.
 
2. Inside the zip file there is a file name “VRMAgent.exe.config” we need to edit this file and replace all references to “localhost” with the “IP” address or “hostname” of the “vCAC server“.
 
3. Next place the files in a folder on an open share where they can be accessed during the sysprep operation.

vCloud Automation Center – vCAC 5.1 – Executing Scripts with the Windows Guest Agent

There are a few components to executing scripts in a Windows Guest OS which I’m going to cover in this post. Those items are:

  • Windows Guest Agent
  • Custom Properties

Windows Guest Agent – UPDATED!

Note: Due to a bug in this version of the agent installer that prevents it from being properly removed from the guest machine I recommend you use the process I define in Automated Install of Windows Guest agent to install the agent. You can follow the article and automate the installation or perform the steps manually in your template to achieve the same result as outlined in this article, without the side affect of the agent staying resident on your deployed machines.

The Windows Guest Agent has a number of feature benefits that you receive if you utilize it. The Windows guest agent is a small agent that acts very similarly to the vCAC proxy agents. When it is installed you give it the name or IP address of the vCAC server. This allows it to check in with the server when it loads on a newly provisioned machine and determine if there is anything it needs to do. If the vCAC server has work for it to do it send the instructions and the agent executes the instructions on the local guest operating system. Once the guest agent is finished performing the work assigned the last process it executes is to remove itself from the guest. The guest agent comes with a number of pre-built functions, but also allows you to execute your own scripts. Some of the features available with the Windows Guest Agent are:

Disk Operations – Partition, Format, and mount disk that is added to the machine.
Execute Scripts – Execute scripts after the machine is provisioned.
Network Operations – Configure setting for additional network interfaces added to the machine.
