The following wizard pages are common to the wizards for deploying virtual machines (from the library) and migrating virtual machines (between hosts).

For more information, see these procedures: How to Migrate a Virtual Machine¸How to Deploy a Virtual Machine.

Wizard Page Action

Select Host

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.

  1. To see the placement settings used to rate the hosts, and optionally change those settings, click Customize Ratings to open the Customize Ratings dialog box.

    You can choose between two placement goals—either resource maximization on individual hosts or load balancing among hosts—and set the relative importance of the availability of CPU, memory, disk I/O capacity, and network capacity for the virtual machine. For more information, see "How Virtual Machine Manager Rates Hosts" ( If you change settings, the host ratings will be repeated to apply the new settings. When you finish reviewing settings, close the dialog box.

  2. To view additional information about a host rating, select the host in the list. The tabs in the details pane beneath the list provide the following information:

    • Details—Displays the status of the host and lists the virtual machines that are currently deployed on it.

    • Ratings Explanation—If a host receives a zero rating, this tab lists the conditions that caused the rating.

    • 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.

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.

Select Path

Select the path to the folder that will store the configuration files for the virtual machine on the host.

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.

Select Networks

Modify the networks and attach them to None or to any of the virtual networks that are found on the selected host.

Networks area lists each virtual network adapter that is attached to the virtual machine. Each network adapter defaults to None if you selected None in the hardware configuration or to the best matching virtual network according to the network matching rules.

Additional Properties

To enable optional actions when the Virtual Server service starts and stops, you must specify the account that the virtual machine will run under for Virtual Server. This setting does not apply to Hyper-V or VMware.

If the hardware supports hardware-assisted virtualization, and you would like to use that feature with the new virtual machine, select the Use Hardware Assisted Virtualization check box.


Review the configuration settings. To change settings, click Previous. To begin creating the virtual machine, click Create.

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.
