Quoting from official announcement:
The ProLiant Essentials Virtual Machine Management Pack (VMM) provides central management and control of virtual machines from Microsoft and VMware. Integrated with HP Systems Insight Manager, VMM provides unified management of virtual machines and supporting HP ProLiant host server resources. This integrated approach provides the ability to manage both physical and virtual resources from a single management console.
VMM simplifies day-to-day management and operation of virtual machines by providing host to VM association and remote access to VM control functions (including start, stop, suspend and reset). VMM also provides at a glance view of VM and host server resource consumption. Using VMM, IT administrators can easily identify VMs or host servers reaching high CPU, memory or disk utilization levels. VMM provides the ability to easily move VMs between host server resources to balance the workload across host servers and better optimize use of datacenter resources. In the future, VMM will also provide the foundation for automating Physical to Virtual (P2V) migrations.
