Separation of Windows updates and Hotfix for Hyper-V R2      Hans Vredevoort ... tonysoper   |   Edit   |   Show History
I would like to see separate lists for Hyper-V R2 updates and hotfixes
Possibly even a subset for Hyper-V R2 and DPM2010 required hotfixes

Currently:
KB975354 - VSS Backup of Hyper-V VM's with DPM2010
KB974909 - The Network Connection of a running Hyper-V virtual machine is lost under heavy traffice on a Windows Server 2008 R2-based computer
KB975921 - You may be unable to perform certain disk-related operations after an exception when a hardware provider tries to create a snapshot in Windows Server 2008 R2 or in Windows 7

>>Hans, thanks for your suggestion. We have begun the process of putting up a separate page for R2 updates. We will post a notice here and on blogs/twitter accounts when the new page goes live.
