To import a virtual machine template from vCenter
In the left pane, select VM Templates.

Select vCenter and select a virtual machine that is not managed by Lab Manager.
(Optional) Deselect the Perform customization check box if you do not want Lab Manager to customize the network settings for the virtual machine template or virtual machines based on the virtual machine template.
Specify the networking information for each NIC in the imported virtual machine template:
