How to Run Dynamic Optimization on a Host Cluster

Applies To: System Center 2012 - Virtual Machine Manager, System Center 2012 R2 Virtual Machine Manager, System Center 2012 SP1 - Virtual Machine Manager
Use the following procedure to run Dynamic Optimization on demand on a host cluster in System Center 2012 – Virtual Machine Manager (VMM). Through Dynamic Optimization, VMM can balance load among hosts by migrating virtual machines within a host cluster. VMM only performs Dynamic Optimization on host clusters that support live migration. On demand Dynamic Optimization does not require that Dynamic Optimization be configured on the parent host group.
For more information about Dynamic Optimization, see Configuring Dynamic Optimization and Power Optimization in VMM.
Account requirements Administrators can run Dynamic Optimization on a host cluster. Delegated administrators can run Dynamic Optimization on host clusters that are within the scope of their Delegated Administrator user role.
How to run Dynamic Optimization on a host cluster
Open the Fabric workspace.
On the Fabric pane, expand Servers, expand Host Groups, and navigate to the host cluster on which you want to run Dynamic Optimization. Then click the host cluster to select it.
On the Folder tab, in the Optimization group, click Optimize Hosts.
VMM performs a Dynamic Optimization review to determine whether virtual machines can be migrated to improve load balancing in the host cluster. If migrating virtual machines can improve load balancing, VMM displays a list of virtual machines that are recommended for migration, with the current and target hosts indicated. The list excludes any hosts that are in maintenance mode in VMM and any virtual machines that are not highly available.
To perform Dynamic Optimization on the host cluster, click Migrate.
