Problem statement:
We are in the process of converting our provisioning code from utilizing conventional Templates stored in specific datastores to leveraging a Content Library per datacenter to allow templates to be used across a larger surface area. Reading through the documentation for PowerCLI New-VM doesn't support the -OSCustomizationSpec when the VM is being created from a Content Library.
Question:
Is there a way via powershell and powercli (or other means) to set the OS Customization Spec after a vm has been created via New-VM? If so, what am I missing?
Notes:
Current snippet is as follows.
