You can create virtual machines in the library from a blank virtual hard disk, from an existing virtual hard disk, or from an existing virtual machine. To use the virtual machine, deploy it to a host by using the Move-VM cmdlet. To store a virtual machine in the library, you must stop the virtual machine, shut down the virtual machine, or place the virtual machine in a saved state. Then, you can use the Store-VM cmdlet to store the virtual machine.

The following script creates a virtual machine in the library from a blank virtual hard disk. Then, the script deploys the virtual machine on the best-rated host in the host group. Finally, the script stops the virtual machine and stores it in the library.

#                  on host ratings. Finally, the script stops the 
#                  virtual machine and stores it in the library.
