Greetings folks,


Today, I've got a guest poster, Carmen Asher, one of my colleagues in VMM team. Carmen is the program manager responsible for SCVMM Configuration Analyzer 2008. Her post below provides you with all the information you need to know on: what VMMCA is all about, where to download it, how to use it, and she is nice enough to even prepare a section of frequently asked questions.

Take advantage and enjoy this free and powerful tool for VMM 2008!




Hi, I am Carmen Asher, Program Manager on System Center Virtual Machine Manager.  I am using a spot on Cheng’s blog to  announce the Public Release to Web of the Virtual Machine Manager Configuration Analyzer 2008.




Customers have come to rely upon, and appreciate, the added value that VMMCA tool provides, so getting it out within weeks of RTM is critical for customers to assist in helping  plan implementation and then also provide value-add during  the ongoing operational phase of SCVMM 2008.  




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 can use VMMCA before installing VMM, to help you evaluate the configuration of computers that you might use for the following VMM roles:

·      VMM server

·      VMM Administrator Console

·      VMM Self-Service Portal


You can also use VMMCA after installing VMM, to evaluate the configurations of computers that you are now using or might use for the VMM roles listed above, as well as computers that you are using or might use for any of the following VMM functions:

·      Windows Server–based host

·      VMware Virtual Center Server

·      P2V source computer

·      Operations Manager agent


System Requirements:

Before you install the VMMCA, you must download and install the 64-bit version of Microsoft Baseline Configuration Analyzer (MBCA). To download the MBCASetup64.msi file, go to


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.


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

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.


Scenario 5 – I am using SCVMM 2008 to do P2V conversions and the job is failing.  Use VMMCA 2008 to check the P2V source for commonly known issues.


Scenario 6 -  I tried to create a Virtual Machine and it failed during customization and installation of virtual guest services.  Use VMMCA 2008 on the Windows Host to find commonly known issues.
