vRealize Automation – vCAC 6.1 – Custom Property Toolkit for vCO

For those of you who have not seen this yet, it is a must have for anyone writing vCO workflows for vCAC.  VMware’s own Dan Linsey build a set of pre-built workflows to help aid you in your own development efforts.  The toolkit includes workflows for performing Create, Read, Update, & Delete Operations for vCAC custom properties for more than just virtual machine objects.  IT includes support for the following:


  • Blueprints
  • Build Profiles
  • Business Groups
  • Endpoints
  • Property Dictionary
  • Virtual Machines
  • and more

vCloud Automation Center – vCAC 6.0 – Configuring Linux Logical Volumes (LVM) using the vCAC 6.0 Linux Guest Agent

More and more frequently I get asked about support for configuring LVM(Logical Volumes) in Linux guests provisioned by vCAC. The short answer is the guest agent by default will partition a disk as a standard Linux partition. However because the guest agent allows us to execute scripts we can overcome this and configure LVM volumes within the guest. In this article I’m going to to walk you through just how to do that.

Using the Linux Guest Agent to config LVM

  1. To begin we need a working vCAC environment that can provision Linux VM’s with a working Linux Guest Agent. You can find information on all the needed topics to install and configure vCAC 6 here.
  2. Next we need a script that we will use to setup the LVM inside the guest Linux operating system. Below I have a very basic script for this example. This script assumed only one additional hard disk will be added to the VM. Any additional disks will not be included in the LVM.

vCloud Automation Center vCAC 6.0 – Using Linux Kickstart to Provision to Physical HP Server over iLo

That big ole title pretty much says it all. In this article I’m going to walk through how to deploy RHEL (Centos) Linux onto a Physical HP Server over the iLo interface using Kickstart. When provisioning to Physical servers such as an HP Proliant DL360 there are two methods built into vCAC. One is the use of PXE boot, and the other is via the iLo interface.

There are pro and cons to both PXE and remote mounting an ISO over the iLo interface. PXE has the obvious cons of the network requirements, having a PXE server available and if you want true flexibility you will need to do a little custom work. ISO mount over iLo tend to be a bit slower due to the over head of remote mounting a ISO and the speed of the iLo interface. In this article I will be covering remote mounting an ISO over iLo, but I will be covering PXE is a later article.

What do we need

To start we need the Physical HP server to be racked and cabled up. It’s iLo interface should be configured and licensed, the network interfaces should be cabled in and the switches should be configured for the appropriate Vlans etc. The drives in the server should also be initialized. vCAC will not create any raid groups etc for you, you must do this manually. My examples also requires a web server that can be utilized to store the needed files on the network.

vCloud Automation Center – Active Directory Computer Account Management Extension


A common extension requested for vCloud Automation Center is the ability to pre-create computer account objects in Active Directory in a specific Organizational Unit, and also to decommission the accounts in different ways along with the virtual machine. Without a custom workflow, you can have the computer join the domain during the customization phase, but this will only create the computer account in the default Computers container. Also, while there is an out-of-the box AD machine cleanup plugin which can be enabled, it will likely never support the multi-tenancy introduced in vCAC 6.0. vCO does not support it today either, but it is more likely to gain support in the near future.

This solution implements these functions using vCenter Orchestrator and its plugins for vCAC and Active Directory.

The rest of this article contains instructions on installing and configuring the vCAC AD Computer Account Management Extension. This extension allows administrators to model very specific OU structures for their AD machine accounts using vCAC custom properties, and supports dynamic OU Distinguished Name building based on combinations of properties derived from different areas of vCAC (compute resources, reservations, groups, blueprints, etc.).

This extension is [Read more…]

vCloud Automation Center – vCAC 5.2 – Virtual Machine LifeCycle Demystified

vCAC has what is referred to as the “Master Workflow” which makes up the Virtual Machine Lifecycle. The Master workflow is the top level workflow states that a virtual machine will go through, throughout it’s life. These workflow states tie pretty closely to the Workflow stubs that are shipped with the designer, but they are not a direct match to them. I often see confusion around the workflow states and the workflow stubs. I’m hoping to clear up the confusion around this and help everyone understand the difference between them.

Master WorkFlow States

The vCAC Master workflow states are as follows:

  1. Request State
  2. Approval State
  3. Provision State
  4. Manage State
  5. Expired State
  6. Decommissioned State
