Environment
- App Control Server: 8.7+
- App Control Agent: 8.7+
- VMware Horizon Instant Clone Desktop Pool
Objective
How to Create Template Image for Instant Clones
Resolution
- Install all required software before installing the App Control Agent (for new installs).
- In the Console > Assets > Computers > relevant Computer (Golden Image) > open the Details > Verify:
- Shutdown the Golden Image.
- In the Console > Computer Details page > right hand menu > Advanced > Create Template Image.
- After clicking OK to the Warning the Template Details page will load for the new Template Computer.
- At this time, initiate a Snapshot of the Golden Image in the VSphere Console & Redeploy the Pool using the new Snapshot.
- Return to the Console and from the Template Details page specify the:
- Template Name
- Clone Inventory settings
- Clone Cleanup
- The defaults for Internal Template should be used:
Internal Template: Standard
Check the box if Clones are joined to an Active Directory domain
Prefix: IT
Suffix: Leave blank
Which characters may exist between the prefix and suffix?
Check the box for "Numbers (0-9)" only
- Internal Template Tests: this is used to verify the Instant Clone VM names don't accidentally match the Internal Template name. If they do, this would cause the App Control Clone process to fail.
- A sample Template Configuration will look like this:
- Save the Template.
Additional Notes
- The Template Image option should only be used for Instant Clones.
- Reverting the Golden Image to a previous Snapshot will cause the Server to see this as a new Instant Clone and the Unlink process will be required.
- The Template Computer option should but used for all other Clone types, and should no longer be used for Instant Clones.
- Updating the Template Image should follow the same process, always use the original Golden Image. Do not use a Clone of a Template.
- The Golden Image may get removed from Assets > Computers due to Old Computer Cleanup. This will not impact the Template Computer or the Clones.
- When the Golden Image is booted again, it should show in Assets > Computers again.
- Unlinking the Clone in Step 2 will require a new Initialization and File Synchronization.
- Many customers choose the Clone Inventory option, "New and modified files" for Non-persistent environments for performance reasons.
- More details can be found in the App Control User Guide chapter, "Managing Virtual Machines".
