It happens that you need to find issues, yes, trust me it happens even for me… and here is how:
To enable VMM debug logging, use the following steps:
- Create a folder called C:\vmmlogs.
- Open an elevated PowerShell window on the VMM server or host computer and run the following commands (the second command may wrap in your display):
logman delete VMM
logman create trace VMM -v mmddhhmm -o $env:SystemDrive\VMMlogs\VMMLog_$env:computername.ETL -cnf 01:00:00 -p Microsoft-VirtualMachineManager-Debug -nb 10 250 -bs 16 -max 512 -a
- Start the trace by typing the following command in the elevated PowerShell window:
logman start vmm
- Reproduce your issue.
- As soon as you reproduce your issue, stop the trace by typing:
logman stop vmm
- Switch to C:\vmmlogs.
- To convert the trace, type the command:
Netsh trace convert <filename>
- Read file, find issue, fix, have a nice day.

Yes, it is finally here and the major “thing” is that it fully supports Dynamic Memory and RemoteFX (included in SP1 for Windows Server 2008 R2). In most cases you download the Service Pack, apply it and you are done, but that is NOT the case this time. What you do is to download the complete ISO image and install that. There are reasons, one being that once you have installed SP1 you cannot go back to RTM, since the database has been modified and Microsoft would like to be sure that you have the complete package (the ISO) so that you can perform a disaster recovery operation. Well, ok, but still I think it would have been better if they did release it as a SP trough WSUS, but that is me. Anyway, here are the steps:
Download System Center Virtual Machine Manager 2008 R2 SP1 (read more about different locations and different licensed version here)
- Perform a backup of the SCVMM Database (just to be safe)
- Mount the ISO on the server
- Install SCVMM 2008 R2 SP1 (It will detect that you are running RTM and upgrade itself)
- Stop the SCVMM service
- Uninstall the Console
- Install the SP1 Console
- Start the SCVMM Service
To be honest, not sure that you need to uninstall/re-install the console, but if I did not do that I could not use/see the new features. When I did, it worked like a charm.
