Your changes are saved on the disk image when you shut down your virtual machine in Virtual PC 2004 (834313)
The information in this article applies to:
- Microsoft Virtual PC 2004
SYMPTOMS When you shut down your Microsoft Virtual PC 2004 virtual
machine, your changes may be saved on the disk image.CAUSE This behavior may occur if the Undo Disks
feature is not turned on for the virtual machine that you are using.RESOLUTION To resolve this behavior, turn on the Undo
Disks feature for the virtual machine where you want to undo changes. To do so, follow these steps:
- Start Virtual PC 2004.
- In the Virtual PC console, click the virtual machine where
you want to turn on the Undo Disks feature, and then click
Settings.
- Click Undo Disks, and then click to
select the Enable undo disks check box.
Notes- If the
virtual machine is running or in a saved state, the Enable undo
disks feature is not available. Therefore, you cannot change the Enable undo disks
feature while the virtual machine is running or in a saved state.
- Virtual PC 2004 creates an undo disk for each virtual hard
disk that is configured on the virtual machine.
- If the Enable undo disks feature is turned
on, any changes that you make during a virtual machine session are saved to an undo disk
(.vud) file. An undo disk file is a temporary file and is separate from the
virtual hard disk. The undo disk file is stored in the same folder as the
virtual machine configuration (.vmc) file. When you close the virtual machine,
you can delete the changes that are stored in the undo disk, commit them to the virtual
hard disk file, or saved them for later. When you delete or commit the changes, the
temporary file is removed.
- If an undo disk file exists, and you turn off the
Enable undo disks feature, or if you configure the Hard Disk 1
setting to use a different hard disk, Virtual PC deletes the undo disk.
Virtual PC prompts you to verify this action before it deletes the undo disk.
