when we need to create a VM template, do we need first to use a powered on VM , then "Clone to Template" ?
after the template has been created do we need to customize the VM so that it will have unique SID?

I might have posted similar question in the past, but since I have not used it, I forgot about the answer.

Thank you

Template creation can be completed with the VM Power ON or Powered OFF.

using the Clone to Template feature.

When Deploying the TEMPLATE, if you want the VM to have a Unique SID, you will need to use the Customization Specification Option to "Sysprep" after deployment.

ALL Physical or Virtual Computers SHOULD HAVE Unique SIDs as recommended by Microsoft, when cloning a computer.

1 - Create a VM.

2 - Convert it to the template and shut it off since templates should not be turned on     anyways.

3 - Clone it from that template.

4 - Do not need to run sysprep if cloned from a template.


Sysprep is needed if cloned from a non-template.

Cloning is possible whether you are cloning from a VM that is turned off or on.

@rajivkumar07, if you used your method, wouldn't all your VMs have the same SID?

You know I forgot to add something else. Here it is -

When the template is created, run the sysprep /generalize and shut it down!!! It will basically rip the Unique identifier.

After that, create a VM by cloning that particular template and at the boot time, that VM will generate its new SID so no need to run sysprep again.

This is what I have been doing in my organization and never got into an issue.

This is what Customization Specification does automatically at Deployment with no interaction with the VM.
