One of the best things about Microsoft products is the thriving community that drives a lot of articles outside of TechNet.  For example there is a Wiki article that describes the Hyper-V updates for Windows 2008 and also for Windows 2008 R2.

 

Windows Server 2012 Hyper-V List of Updates on TechNet 

 

The community has also started to publish the Windows Server 2012 Hyper-V update list.

 

 

Currently there are only a couple of updates, but this will be refined over time as updated KBs are released to remediate issues.

 

 

 

 

 

 

 

 

In addition to the Hyper-V list of updates you may also want to look at the update list for the cluster service in Windows 2012.    For example this also covers the console crash issue caused by .NET update 2750149.
