How to Configure Host Group Properties in VMM


Applies To: System Center 2012 SP1 - Virtual Machine Manager, System Center 2012 R2 Virtual Machine Manager, System Center 2012 - Virtual Machine Manager

You can use the following procedure to configure host group properties in Virtual Machine Manager (VMM).

To configure host group properties

  1. Open the Fabric workspace.

  2. In the Fabric pane, expand Servers, expand All Hosts, and then click the host group that you want to configure.

  3. On the Folder tab, in the Properties group, click Properties.

  4. Configure any of the following settings:




    Configure the host group name, the location in the host group hierarchy, the description, and whether to allow unencrypted BITS file transfers.

    Placement Rules

    VMM automatically identifies the most suitable host to which you can deploy virtual machines. However, you can specify custom placement rules. By default, a host group uses the placement settings from the parent host group.

    Host Reserves

    Host reserve settings specify the amount of resources that VMM sets aside for the host operating system to use. For a virtual machine to be placed on a host, the host must be able to meet the virtual machine’s resource requirements without using host reserves. You can set host reserves for individual host groups and for individual hosts. The host reserve settings for the root host group, All Hosts, sets the default host reserves for all hosts.

    You can configure reserve values for the following resources:

    • CPU

    • Memory

    • Disk I/O

    • Disk space

    • Network I/O

    Dynamic Optimization

    Configure dynamic optimization and power optimization settings. Dynamic optimization balances the virtual machines load within a host cluster. Power optimization enables VMM to evacuate hosts of a balanced cluster and turn them off to save power. For more information about these settings, see Configuring Dynamic Optimization and Power Optimization in VMM.


    View inheritance settings, and configure whether to inherit network logical resources from parent host groups. The network logical resources include the following:

    • IP address pools

    • Load balancers

    • Logical networks

    • MAC address pools


    View and allocate storage to a host group. For more information, see the following topics:

    • Virtual machine

    • Virtual machine template

    • Host

    • Host cluster
