VM Recovery Tool
The stand-alone Virtual Machine Recovery Tool works with System Center 2012 – Virtual Machine Manager (VMM) to temporarily remove a host, cluster, virtual machine, or service from VMM when that object is in a failed or persistent warning state due to environmental conditions, third-party applications, or other causes. After resetting the state of the object, once VMM refreshes, the object will appear as healthy in VMM. This tool does not repair a damaged or incorrectly created virtual machine or corrupt .vhd file. It deals with state information stored in the VMM database. For additional details about the tool, see Using the Virtual Machine Recovery Tool for System Center 2012 - Virtual Machine Manager (VMM).

Important
This program is not a supported part of the VMM product. This program is offered “as-is”.

Virtual Machine Manager Configuration Analyzer (VMMCA)
The VMMCA is your first line of defense in troubleshooting an issue in the System Center 2012 – Virtual Machine Manager environment. VMMCA is a diagnostic tool you can use to evaluate important configuration settings for computers that are either running VMM server roles or are acting as virtual machine hosts. The VMMCA scans the hardware and software configurations of the computers you specify, evaluates them against a set of predefined rules, and then provides you with error messages and warnings for any configurations that are not optimal.

Microsoft Product Support Reporting Tool (MPSRPT)
You can use the Virtual Machine Manager MPS Reporting Tool for System Center 2012 to gather detailed system status and configuration information from the VMM management server as well as all managed virtual machine hosts and VMM server roles.
The tool offers the ability to select the particular scenarios for which system configuration data will be gathered.
The Virtual Machine Manager MPS Reporting Tool for System Center 2012 gathers the following diagnostic data for the VMM management server, the virtual machine hosts and library servers that the VMM management server manages, and physical to virtual conversion (P2V) source computers:

• Virtual Machine Manager traces
• Virtual Machine Manager database
• Windows event logs and virtual server event logs
• IP address
• Virtual Machine Manager setup logs
• SQL Server setup logs
• Registry information
• Open ports information
• System Information (msinfo)

OVF Import/Export
The Open Virtualization Format (OVF) is a packaging standard from Distributed Management Task Force, Inc., for portability and deployment of virtual appliances. The OVF Import/Export tool consists of cmdlets that enable VMM users to import and export single virtual machines that are packaged in an OVF 1.1 complaint format. You can use the OVF Import/Export tool to import a virtual machine from other virtualization platforms (currently VMware vCenter and Citrix XenServer) or to export a virtual machine from VMM for use on another platform.
