Whether you are currently running Hyper-V or just getting started, Microsoft has released a great toolset that will help guide you towards a better, more efficient virtualization environment.
You can use this Analyzer to run Powershell scripts to check on a group of servers on how they compare to BPA or run it for a single server. Check it out at: http://support.microsoft.com/kb/977238
Best Practices Analyzer (BPA) is a server management tool that is available in Windows Server 2008 R2. BPA reports best practice violations to the administrator after BPA scans the roles that are installed on Windows Server 2008 R2.
This download contains best practice benchmarks against a computer that is running Hyper-V on a computer that is running Windows Server 2008 R2. With this update, you can run a series of Best Practices Analyzer scans on Hyper-V that will help you to bring the role into compliance with best practices.
You can use Hyper-V Best Practices Analyzer to scan a server that is running the Hyper-V role, and help identify configurations that do not comply with best practices for this role. BPA scans the configuration of the physical computer, the virtual machines, and other resources such as virtual networking or virtual storage.
Scan results are displayed as a list that you can sort by severity, and include recommendations for fixing issues and links to instructions. No configuration changes occur automatically by running the scan. More information about Hyper-V is available at http://go.microsoft.com/fwlink/?LinkId=48557
