- 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.
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.
