File system security settings for Virtual Server

File system security settings

The ability to view and specify configuration settings for Virtual Server 2005, virtual machines, virtual networks, and virtual hard disks is controlled by discretionary access control lists (DACLs) on the Virtual Server folders and files.

This topic describes the DACLs that are configured by default for these folders and files. These DACLs give members of the Administrators group on the computer running the Virtual Server service full control over Virtual Server, virtual machines, virtual networks, and locally stored virtual disks.

For more information about configuring these settings to allow users to access and control Virtual Server and its components, see Configuring Virtual Server security settings, Configuring virtual machine security, and Configuring virtual disk security.

DACL for the Virtual Server folder

Virtual Server Setup creates the Virtual Server folder, which is located by default in C:\Documents and Settings\All Users\Application Data\Microsoft\. The Virtual Server folder contains the following items:

  • Virtual Server configuration file (Options.xml)
  • Virtual Server license file (VSLicense.xml)
  • Virtual Machines folder, which contains shortcuts to the configuration files of virtual machines that are currently configured on Virtual Server
  • Virtual Networks folder, which contains shortcuts to the configuration files of virtual networks that are currently configured on Virtual Server

The DACL on this folder applies to the folders and files that it contains. The following table lists the default access control entries (ACEs) of this DACL. Although you can configure this DACL from within the file system, we recommend that you instead use the Virtual Server Security Settings page of the Administration Website. For instructions, see Configure Virtual Server Security Settings.

The default DACL for the Virtual Server folder is shown in the following table.
