HVRemote reduces the manual configuration steps needed for Hyper-V Remote Management down to one or two commands.
It can configure Full installations and Server Core Installations of Windows Server 2008 with the Hyper-V role enabled, plus configure Microsoft Hyper-V Server. It runs across all locales (I’ve tested English and Japanese) and it doesn’t matter if the server is domain or workgroup joined.
It can configure Vista SP1 and Server 2008 configured with the Hyper-V Remote Management tools. Again, doesn’t matter if the client is domain or workgroup joined.
