You have a Windows Server 2008 R2 Hyper-V failover cluster with a single iSCSI logical unit number （LUN） and one highly available virtual machine （HAVM）. You manage the virtual environment by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2. You monitor the environment by using Microsoft System Center Operations Manager 2007 R2. You configure a new virtual machine （VM） by deploying a VHD from the VMM library and placing the VHD on the existing iSCSI LUN. You create a HAVM configuration， and you attach the VHD to the configuration. VMM reports the status of the VMs as Unsupported Cluster Configuration. You need to be able to manage the VMs by using VMM. What should you do？（）

A. Move the VHD of one HAVM to a new iSCSI LU
B. Move the VHD of one HAVM to the system volume of a cluster node.
Configure Performance and Resource Optimization （PRO） on the Windows Server 2008 R2 cluster nodes.
D. Configure Windows System Resource Manager （WSRM） on the Windows Server 2008 R2 cluster nodes.
