Virtual Machine Manager 2008 and 2008 R2 Configuration Analyzer (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. VMMCA scans hardware & software configurations of computers you specify, evaluates them against a set of predefined rules, and then provides you with error messages & warnings for any configurations that aren’t optimal for VMM role or other VMM function that you’ve specified for the computer. Requirements: You must install & run VMMCA on computer that either currently is or will become your VMM 2008 server. To review system requirements for VMM 2008 server, go here. Prerequisite: Microsoft Baseline Configuration Analyzer (MBCA). Note: System requirements for MBCA indicate that only Windows Server 2003 is supported. However, VMMCA and MBCA have been tested and are supported on Windows Server 2008 64-bit.
