When migrating from SCVMM 2008 Beta to the final release bits (RTM), a utility is required in order to complete the process successfully. This tool is no longer posted on the Microsoft 'Connect' site, but is still available by request from Microsoft Support. The name of the utility is 'upgradev2beta.exe'.

Collecting traces while reproducing an issue is one of the best methods we have of determining the source of an issue. Microsoft engineers might ask for this information when you open an incident, or you may want to perform tracing on your own for review. Cheng wrote the original article that walks you through the process step-by-step. With the growing number of Windows Core installations a colleague of mine (MikeB) found that new instructions were needed to perform this same process. Bookmark his post. It's one for the toolbox.

How to capture a Dbgview trace from Windows Core

Here it is. We have a new KB that details updates and hotfixes required for SCVMM, Hyper-V and Clustering. Read the article here.

I've commented on the hotfixes inline below, providing a Support Engineer's perspective.

________________________________________________

Required hotfixes for Hyper-V servers

Install these. No question.

• 956589  (http://support.microsoft.com/kb/956589/ ) Description of the Hyper-V update for issues that may occur when you manage the Hyper-V role on the 64-bit editions of Windows Server 2008 by using SCVMM
• 956774  (http://support.microsoft.com/kb/956774/ ) A Background Intelligent Transfer Service (BITS) client cannot handle files that have paths that contain the volume GUID in Windows Server 2008 or in Windows Vista

• 950050 (http://support.microsoft.com/default.aspx?scid=kb;EN-US;950050/ ) Description of the update for the release version of the Hyper-V technology for Windows Server 2008
  

Note If these hotfixes are missing from a Hyper-V server, the System Center Virtual Machine Manager 2008 Admin Console lists the server status as Needs Attention. Hotfix 956774 should be installed on the Hyper-V servers and on System Center Virtual Machine Manager 2008 Server.

Recommended hotfixes for the Hyper-V servers

Install ALL hotfixes on ALL Hyper-V servers, whether SCVMM is involved or not. This is more than a recommendation based on cases I have worked.
