Two weeks ago Microsoft released an update for Windows Server 2008 to improve the failover capabilities when the OS is configured to work as Hyper-V parent partition.
The package includes a long list of enhancements:
- Changes to the virtual machine view
- Changes to virtual machine actions
- Allow for more than one virtual machine in a “Services or Applications” group
- Add support for mount points or volumes without a drive letter
- Changes to the virtual machine refresh action
- Behavior changes if any node of the failover cluster has a disconnected virtual machine
- Behavior change when you add a pass-through disk to a virtual machine
- Behavior change when the parent differencing disk is not on shared storage
- Volume path copy
Microsoft anyway doesn’t seem 100% confident on the reliability of its own fix as it warns:
Apply this hotfix only to systems that are experiencing this specific problem. This hotfix might receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next software update that contains this hotfix.
