I have two Virtual Servers configured using HyperV. These servers have the Mailbox role installed on them, with a DAG configured for HighAvailability. The DAG seems to be working fine, but when I run the Exchange Best Practice Analyzer for exchange 2010 on get an error on my 2nd mail Server, that says the following:
-Unsupported Virtual Machine Configuration - Clustering
When I click the link that says "tell me more about this issue and how to resolve it", it says the following:
The Microsoft® Exchange Server Analyzer Tool queries the Win32_ComputerSystem Microsoft Windows® Management Instrumentation (WMI) class to determine whether the value for the Model key is set to "Virtual Machine".
The Exchange Server Analyzer also queries the Win32_Service WMI class to determine the value of the Started key for ClusSvc, the Windows Cluster service. A value of True for the Started key indicates the Cluster service is started, and a value of False indicates the Cluster service is not started.
The Exchange Server Analyzer displays an error if the following conditions are true:
• The value for the Model key is set to "Virtual Machine".
• The value of the Started key for the Cluster service is set to True.
This error indicates that the Exchange server is a clustered Exchange server that is running in a virtual machine environment. This configuration is not supported.
To correct this error
1. Build a physical cluster and move the mailboxes to the physical cluster from the clustered Exchange server that is running in the virtual environment.
2. If you cannot build a physical cluster, you can correct this error as follows:
1. Move the mailboxes from the Exchange Server that is running in the virtual environment to a non-virtual, stand-alone Exchange Server computer.
2. Re-home any public folders and transfer any roles performed by the clustered Exchange server as required.
3. Uninstall Exchange Server from the virtual machine to decommission and remove it from the Exchange Server infrastructure and from Active Directory.

Before I installed exchange 2010 High Availability (DAG). I was reading articles that said there was no problem with doing this on HyperV virtual servers. Does Microsoft really not support High Availability on Virtuals? Thanks.
