Sysprep runs unexpectedly at each deployment of a cloned template (1007349)
When a template is deployed Sysprep is run every time the virtual machine is started
The template has been cloned from another copy of a Lab Manager configuration using VirtualCenter to create the clone
If a new template is created by using VirtualCenter to clone an existing Lab Manager configuration and imported back to Lab Manager as a template, Sysprep may run every time the template is deployed.
This issue occurs because during deployment, lm-tools determines if it needs to run sysprep by checking for the presence of a machine.id in the virtual machine's .vmx file. If this entry is present, lm-tools, and therefore sysprep, runs. In this circumstance the cloned copy already has an entry and is stored in the template so each deployment triggers Sysprep.
To prevent sysprep from running unexpectedly:
Undeploy the template in Lab Manager.
Connect to the service console of the ESX host as root.
Open the .vmx file for the template in a text editor.
Remove the line that contains the machine.id value.
machine.id = "macaddr=00:50:15:3a:00:1c&bootproto=dhcp&computerName=hostname&UseSysPrep=Yes&MARKERID=524341316"
Save the changes.
