Updated System Center Virtual Machine Manager Configuration Analyzer (VMMCA)

devmgr.dll_I00c9_0409 Description

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.
