Using existing virtual machines as templates
You want to use an existing virtual machine as a template for creating new virtual machines on a Hyper-V host in your test environment. Should you register, restore, or copy the virtual machine when you import it onto a host?
Quick check answer
Copy it. This generates a new GUID for each new virtual machine you create with the import process.
