Last week we released the System Center 2012 Management Pack for Hyper-V in Windows Server 2012. You can go grab it here: http://www.microsoft.com/en-us/download/details.aspx?id=36438
One thing I would like to highlight – in the past we have had two management packs for Hyper-V. One written by the Hyper-V team and one written by the System Center Virtual Machine Manager team. Well, we have now done the sensible thing and combined these into one management pack that you can use with or without System Center Virtual Machine Manager.
Cheers,
Ben
