I saw the article:

When you import a VMware template to the VMM library, the .vmdk file is no longer copied to the library. Instead, VMM only copies the metadata that is associated with the template. The .vmdk file remains in the ESX datastore. Because of this relationship, you can deploy virtual machines by using the template much more quickly. Also, when you import a VMware template, VMM no longer deletes the source template.
That means we could only import VMware template and create VM by VMM without .vmdk file in library?
