Enable Undo Disks for a virtual machine

To enable Undo Disks for a virtual machine

  1. Open the Administration Website.
  2. In the navigation pane, under Virtual Machines, point to Configure and then click the appropriate virtual machine.
  3. Click Hard disks in the Configuration section on the lower part of the page.
  4. Click Enable undo disks, and then click OK.
To perform this procedure, you must have the appropriate permissions. If you do not have the appropriate permissions, you will either receive an error message or you will not be able to view certain menu items and options described in this procedure. To change your permissions, contact your Virtual Server administrator. For more information, see Securing Virtual Server. For instructions on opening the Administration Website, see "Open the Administration Website" in Related Topics. The virtual machine must be shut down without being in a saved state before you can enable Undo Disks. The file that Virtual Server creates to store all changes to a virtual machine when using Undo Disks is always located in the same folder as the virtual machine configuration file. When you enable Undo Disks, that action applies to all virtual hard disks assigned to the virtual hard disk. If you want to selectively control changes to only some of the virtual hard disks, use differencing virtual hard disks instead.
