Consider the following scenario:
- You have a Hyper-V guest operating system that is running Windows Server 2008 R2 or Windows 7.
- The guest operating system has a disk that is connected to a SCSI controller.
In this scenario, the following event is logged in the System log:
Event Type: Error
Event Source: Virtual Disk Service
Event Category: None
Event ID: 1
Description: Unexpected failure. Error code:exception code
The VDS looks for the Location paths property of the controller. The value of this property is the path location of the disk. However, a virtual controller doesn't have this property.
This event can be safely ignored.
