The VMMCA is a diagnostic tool you can use to evaluate important configuration settings for computers that either are serving or might serve VMM roles or other VMM functions. 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 for the VMM role or other VMM function that you have specified for the computer.
You must install and run the VMMCA on the computer that either currently is or will become your VMM 2008 server. To review the system requirements for the VMM 2008 server, go to http://go.microsoft.com/fwlink/?LinkId=133516.
Prerequisite: Microsoft Baseline Configuration Analyzer (MBCA)
Note: The system requirements for the MBCA indicate that only Windows Server 2003 is supported. However, the VMMCA and the MBCA have been tested and are supported on Windows Server 2008 64-bit.

Common Usage Scenarios
The list of scenarios are not comprehensive, but will provide you with some common usage scenarios to provide you with an understanding of when to use VMMCA 2008.
Scenario 1 – I have a Windows Host that is in a not responding state. Use VMMCA 2008 to check the host for commonly known issues.
Scenario 2 – A Windows host shows a status of “Needs Attention”. Use VMMCA 2008 to check the this host for commonly known issues.
Scenario 3 – I am using SCVMM 2008 to manage a VMware environment, but I am unable to create new virtual machines on the VMware environment. Use VMMCA 2008 to evaluate the Virtual Center environment for commonly known issues.
Scenario 4 – I am using the integration between SCVMM 2008 and Operations Manager, but I am unable to see a particular VM or Host in the integrated mapping view. Use VMMCA 2008 to check the host or virtual machine for an operations manager agent.
