The DH Forum is intended to be for all things cloud. Currently we have forums created for vCAC, vCD, vCO, Cloud General, and Openstack. More forum categories will be coming based on demand. If you have a category you would like to see shoot us a note and let us know.

Our goal is to create a common place where anyone can come to learn, get help, share ideas, or just about anything that will help foster knowledge regarding cloud computing. Considering this very blog is the announcement of our forum you could image there isn’t a whole lot happening yet so what are you waiting for, be the first. Go ask a question, post an issue, share a thought and let’s get things rolling.

vCloud Automation Center – vCAC 5.1 – Installing Self-Service Portal

vCAC comes with a self-service portal outside the standard portal. The self-service portal is included with the vCAC-51-Extensibiliy installation files.

To install the portal you need to download the VMware vCloud Automation Center 5.1 – Development Kit. In the kit their is an installation file named “DCAC-SelfService-Setup.exe” this is the installer for the Self-Service portal.

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.

vCloud Automation Center – vCAC 5.1 – Creating Custom Drop Down Menu’s

To create a custom drop down menu that can be presented to users at request time we will be leveraging the Property Dictionary. The Property Dictionary gives us the ability to enhance and further customize the request experience. The Property Dictionary allows us to:

  • Create Basic Drop Down Menu’s
  • Create Context Sensative Drop Down Menu’s
  • Create Drop Down Lists
  • Create Checkboxes
  • Create Date/Time inputs
  • Create Noteboxes, TextBoxes, Integer inputs, links, password inputs and more.

Property Dictionary

In this example we are going to create a basic drop down menu that allows a user to select the folder their machine should be placed in inside vCenter from a list of available locations.
