Troubleshooting Composer for VMware Horizon View

***UPDATE: We just published a great troubleshooting KB article for Composer that covers a lot of the common issues customers encounter here.

At some point, every View administrator who uses a linked clone pool is going to need to do some troubleshooting. Most linked clone troubleshooting involves a component called Composer.
What is composer, and what does it do?
Composer is an add-on for VMware Horizon View and is used to build linked clone desktops. Details about linked clones and Composer operations can be found in my previous posts, What is a linked clone? and part II of that topic.

Today we will focus on troubleshooting Composer when it breaks.

We are in the process of compiling a KB which will serve as the go-to article for Composer. This will contain links to important KBs, common issues, and procedures for repair. In the meantime, I thought this tactic would be good to share.

Compatibility

Compatibility is more important than many admins realize. VMware builds, tests, certifies and supports components that are built to work together.

The Connection Server talks to:

  • Composer
  • View Agent
  • vCenter
  • Security Server
  • and the clients

Composer in turn, talks to:

  • vCenter,
  • Connection Server
  • The hosts
  • Active Directory
  • The guest OS

As you can imagine, it’s easy for problems to balloon out of control if a component doesn’t talk properly to another. So, you need to ensure that every component is compatible and is designed to work with every other.

Here's how-

Identifying where a problem exists is the first step to solving it. Composer can be nonfunctional because of factors that are entirely outside of Composer itself. For example, View doesn’t build desktops, that step is done by vCenter through API calls. If you are trying to build desktops and nothing is happening, it doesn’t mean View or Composer are at fault. vCenter needs to be fully functioning properly for View to be able to provision desktops. Along the same lines, Composer needs to be able to talk to all of the hosts in a cluster plus your Active Directory to be able to customize VMs, so if you have a dead host, Composer will fail.

Is Composer at fault then if it doesn’t work? Well, what about the guest VM? Does it get an IP address? Does it boot? If the answer to any of these is no, then Composer can’t do its job.

One of the tactics I take when Composer fails is to manually step though all of the processes involved.

  • Can I clone the base image?
  • Can I change customize it?
  • Can I activate it?
  • Is it network accessible?

If the answer to any of these questions is no, the problem is outside of Composer. Understanding where the linked clone process fails is the key to resolving problems.

Come see us at VMworld!

Once again this year, the folks behind Knowledge Experience are coming to VMworld to showcase all the new things we've been up to since last year. I am sure you are asking why it is called Knowledge Experience – we have a new mission and vision and that is to provide contextual content to the customer to ensure they can solve their issue before they need to create a service request – we are looking for your insights and feedback on how you would like to see this.

Some of you will remember the great vSphere networking posters we were handing out last year. We're happy to announce we have another one - this time for VMware View. All the interconnecting ports/protocols... these look great on the wall! To get yours, come say hello to Rick Blythe at the VMware Communities Info Desk in the Hang Space during these times:

  • Monday: 11am – 2pm
  • Tuesday: 11am – 2pm
  • Wednesday: 1pm – 4pm

That's not all -- in the Solutions Exchange Sharon, Robyn, and Rick have two demos for you:

  1. New My VMware Web Portal prototype
  2. New My VMware iPhone App prototype

We're really pumped to hear what you have to say about how we can provide you more contextual content to help you solve problems before creating a support request and therefore reducing your time and effort so that you can get back to your day jobs - We'll be right next to the My VMware pod.  Our pod is titled:

Using Knowledge to Get Answers Quickly

  • Leverage online self-help support
  • Prevent or resolve problems quickly
  • Provide input to new concierge model

We hope you drop by; we'd love to hear what you think!

See you there!
