Symptoms

Consider the following scenario:
  • You configure a Windows Server 2008 R2-based computer as a failover cluster node.
  • You perform a live migration of a Hyper-V virtual machine from a source node to a destination node.
  • The source node is located on a computer that has an AMD processor that was released earlier than the Bulldozer family of processors. For example, the computer has an AMD Opteron 6100 series processor.
  • The destination node is located on a computer that has an AMD Bulldozer processor. For example, the computer has an AMD Opteron 6200 series processor.
In this scenario, the migration fails, and you receive a message that states that the destination node is incompatible.

Cause

This issue occurs because the AMD 3DNow! technology is deprecated in the AMD Bulldozer family of processors. However, Hyper-V virtual machines incorrectly use the AMD 3DNow! technology when they are in compatibility mode.

Resolution

Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    6.1.760 1.17xxxWindows Server 2008 R2SP1GDR
    6.1.760 1.22xxxWindows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
