Microsoft has released a new Patch for System Center Virtual Machine Manager 2008.
The Patch addresses multiple issues like:
1. virtual mahines have a status of “unsupported cluster configuration”.
2. agent status is not updated for cWindows Server 2008 Failover Cluster nodes.
The update is to be installed on the SCVMM server itself, and it does not require restart,
So I suggest that you apply it immediately.
You can find more information and a link to download the patch Here.
The Update is also available under Windows Updates.
Also, The patch also includes update KB959596 which addressed issues with P2V Conversions.
