This topic describes how to create a new virtual machine that is
based on an existing virtual machine, also known as cloning.
Cloning also allows you to make backups of existing virtual
machines. You can clone a virtual machine that is stored in the
library or a deployed virtual machine that is stopped.
When you clone a virtual machine:
- You cannot make changes to the operating
system settings, but you can make changes to the hardware
- You can clone a virtual machine that is
stored in the library or a deployed virtual machine that is
- The cloned virtual machine has the same
computer name, which is assigned to the guest operating system, as
the source virtual machine. However, if the cloned virtual machine
is deployed on the same host as the original virtual machine, VMM
assigns it a different virtual machine name.
To clone a virtual machine:
- Click a specific virtual machine. On the Actions pane in the
Virtual Machine Manager Administrator Console, click Clone a
- Complete the New Virtual Machine Wizard.
Virtual Machine Identity
Configure the following options:
- Virtual machine name (required). Type
a unique name for the virtual machine.
- Owner (required). The owner must have
a domain account in Active Directory.
- Description (optional). Type a
description for the new virtual machine.
To configure additional hardware for the virtual machine, use
the following procedures:
- Startup Order—Select
the order of devices to start the operating system.
Requirements—Specify processor requirements for the virtual
- Memory—Specify the
amount of memory to allocate to the virtual machine
Drive—Configure the virtual floppy drive to read a physical
floppy disk on the host or to read a virtual floppy disk file
stored in the library.
- DVD or CD Drive—Add
a virtual DVD or CD drive to an IDE bus.
- Virtual Hard
Disk—Add a virtual hard disk to an IDE device or a SCSI
Adapters—Configure one or more virtual network adapters for a
- Priority and
Availability—Configure the virtual machine's priority for CPU
resources on the host. Configure the virtual machine to be highly
Choose between two options:
- Place the virtual machine on a host.
The wizard will continue with the Select Host wizard
- Store the virtual machine in the
library. The wizard will continue with the Select Library
Server wizard page.
(Host placement only)
Select a host to deploy the virtual machine on.
All hosts that are available for placement are given a rating of
0-5 stars based on their suitability to host the virtual
machine. The host ratings are based on the virtual machine's
hardware and resource requirements and anticipated resource usage.
They are also based on placement settings that you can customize
for VMM or for individual virtual machine deployments. The ratings
are recommendations. You can select any host that has the required
disk space and memory available.
- To see the placement settings that were used to rate the hosts,
and optionally change those settings, click Customize
Ratings to open the Customize Ratings dialog box.
- To view additional information about a host rating, select the
host in the list. The tabs below the list in the details pane
provide the following information:
If a host has network optimization enabled, a green arrow appears
in the Network Optimization column. VMM 2008 R2
allows you to take advantage of network optimization capabilities
that are available on Hyper-V hosts that are running Windows
Server 2008 R2. For information about network
optimization and the hardware that supports it, see the Windows
Server 2008 R2 documentation. After a virtual machine is
deployed, this feature is displayed only for virtual machines that
are deployed on a host that is running Windows
Server 2008 R2.
- Details -- Displays the status of the
host and lists the virtual machines that are currently deployed on
- Ratings Explanation -- If a host
receives a zero rating, this tab lists the conditions that caused
- SAN Explanation -- If a SAN transfer
cannot be used to move the virtual machine's files to the host,
this tab lists the conditions that prevent a SAN transfer.
Select Library Server
Select a library server on which to store the virtual
To view additional information about the available library
servers, select the server in the list. The tab below the list in
the details pane provides the following information:
SAN Explanation -- If a SAN transfer cannot be used to
move the virtual machine's files to the library server, this tab
lists the conditions that prevent a SAN transfer.
Select the path to the folder that will store the configuration
files for the virtual machine:
- If you chose Place the virtual machine on
a host, specify the path on the host to which to save files
associated with this virtual machine.
|If you would like to store other virtual machines on this path,
select the Add this path to the list of host default paths
check box to add the path to the list of default paths during
virtual machine creation.
- If you chose Store the virtual machine in
the library, specify the library server that will store the
virtual machine, and then select the path on the available library
shares to store the virtual machine's configuration files. The
wizard will continue with the Summary page.
Modify the networks and attach them to None or to any of
the virtual networks that are found on the selected host.
|The Networks area will list each of the virtual network
adapters that are currently attached to the virtual machine.
Network adapters will default to None if you selected
None in the hardware configuration, or to the best matching
virtual network according to the network matching rules.

Configure actions to take on a virtual machine when the
virtualization service starts and stops. For more information, see
How to Configure
Automatic Start and Stop Actions for a Virtual Machine
Review the configuration settings. To change settings, click
Previous. To begin creating the virtual machine, click
|Use the View Script button to display the Windows
PowerShell - Virtual Machine Manager cmdlets that will perform the
operation. All administrative tasks in Virtual Machine Manager can
be performed at the command line or scripted.
