Problem with a restart of a restored virtual machine: Why did the computer shut down unexpectedly?
An unexpected shutdown message is displayed when a restored Windows virtual machine is started.
When you start a restored virtual machine, the system may display the message "Why did the computer shut down unexpectedly?" It may prompt you to enter a problem ID. This message and prompt occur if the virtual machine was in the Running state when the backup was initiated.
When a Windows system starts up, a bit is set indicating that the system did not shut down gracefully. If the system is shut down gracefully, the bit is cleared. However, when an online backup of a running virtual machine is performed, the unexpected shutdown bit remains set in the backed-up image. When the restored virtual machine is started, the bit is detected and the unexpected shutdown message is displayed.
