Configuring VMware Horizon Instant Clones

I have been testing VMware Horizon Instant Clones for some time now and several people have asked me how I configured instant clones as when they tried to test them either the instant clone option was grayed out or when instant clones is selected the next button is grayed out. The other issue I see is some people have issues deploying instant clones and they fail to deploy.

Below are all of the things to check when configuring View Instant Clones. One of these issues has fixed all of the question I have been asked over the last few week during testing.

Licensing

Make sure you have the correct VMware Horizon license, there is a new license that include the Instant Clone feature. If you do not have the correct license then the option will be grayed out.

View Storage Accelerator

One of the requirements for Instant Clones is to enable the View Storage Accelerator. Before you try and deploy a new Desktop pool using Instant Clones make sure you have configured the View Storage Accelorator on you vCenter server.

1

Select the vCenter Server

If you have the View Storage Accelorator enabled and you select Instant Clones but the Next option is still grayed out make sure to select the vCenter itself.

2

Configure Instant Clone Domain Admin

Make sure you configure the Instant Clone Domain Admin, this account will need to be able to add new computers to your Active Directory.

3

Horizon View 7 Agent

Make sure you install the new Horizon View 7 Agent on to the gold image. There are a couple of things here you need to know

  1. First if you want to use the gold image for View Instant Clones, then during the install of the View 7 agent you need to select this option
  2. If you do select the View instant clone during the install then you can not install the view composer option, it is one or the other
  3. Unlike with view composer with View Instant Clones it is the Agent its self that adds the VM to active directory and not a separate composer server. This make View Instant Clones much more light weight, no extra server or database is needed for View Instant Clones.

If you make sure you have checked all of these things, then I am sure that View Instant Clones will work and you will see just how fast this new option is when deploying desktops.

Final Note

One last thing to Note, you will see a number of new VM’s in your vCenter that relate to your newly deployed instance clone desktops. I have listed these below.

4

cp-template-XXXXXXXXX This is the template VM that will be used to create your Instant Clones, this will be created from your Gold Image. This will be created on the destination storage or your desktops, but under storage you will also see that it is on the same storage as your gold image. You will also notice you can not edit this VM.

cp-replica-XXXXXXXXX this is the replica that is created for your VM parents. This is created from the cp-template and is placed on the destination storage.

cp-parent-XXXXXXXXX you will see one of these for each of the servers in your cluster, so in my case you see 6 as there are 6 ESXi servers in my cluster. These are all created on the destination storage and will be powered on, each ESXi server will have 1 of these cp-parents powered on and in memory ready to create a new desktop.

  1. When you refer to “picking one or the other” in terms of Composer vs Instant clones, do you mean during installation of Horizon or during pool creation?
    I’m struggling to get a working Instant clone pool that doesn’t bomb during the initial push.

    1. During the install of the Horizon Agent, by default its set to install the composer agent. You need to unselect this and select the instant clone agent.
