Applies To: Windows Server 2008

This is preliminary documentation and subject to change.

This aspect refers events relevant to the storage of the virtual machine that are caused by storage configuration.

Event Details

Product: Windows Operating System
ID: 12141
Source: Microsoft-Windows-Hyper-V-Worker
Version: 6.0
Message: Failed to open attachment '%3'. Error: '%4'


Check image

Check and ensure a valid image exists, has the right permissions, and is attached.

You may get this failure if the image, connection, and/or permissions are mismatched. For example, an image file can be a virtual hard disk (.vhd file), or a “virtual” DVD disc (.iso file).  If a text file with a .txt file name extension were renamed with a .vhd file extension, you would get an error that the image is not valid. If you attempted to attach a .vhd virtual hard disk to a SCSI controller and that controller is not supported by the operating system, you would also get an error. You might also get this error if the image is valid, but in a different location than specified, or in the location specified, but not accessible by  the user credential.

There may be multiple issues. You should start with the error message. For example, if the error message states the image "may have been removed from the system" begin by checking the location of the file. If the file is present, check permissions issues.



The virtual machine with the storage attached is able to launch successfully.
