Computer stops responding or restarts during Hyper-V Live Migration on Windows 2008 R2
Hyper-V Issue that can affect SCVMM operations
What: A new article has been released with a hotfix to resolve an issue where Windows 2008 R2 servers running on AMD Family 10h processors may restart unexpectedly or stop responding. No error messages are generated.
When: Issue may occur when the Live Migration feature is used to move a virtual machine (VM) from one Windows Server 2008 R2 Hyper-V based node to another. This implies that the nodes are members of a Failover Cluster. This problem usually affects the source node that is the original location of the VM.
Why: Erratum 383 in AMD Family processors generates a machine check exception.
Hotfix Information: To apply the hotfix the computer must be running Windows Server 2008 R2. You may have to restart the computer after installing the hotfix.
SCVMM Note: Install this hotfix on all Windows Server 2008 R2 systems that are nodes of a Failover Cluster.
