How to Configure Image Pre-staging

Note   Image pre-staging is useful only for the initial image download. It is not supported for image update.

How to Configure Image Pre-staging

To configure image pre-staging

1. On the client computer, under the image store directory, create a folder for the pre-staging image, and name it MED-V Images.

   Note   This folder must be called MED-V Images.

2. Inside the MED-V Images folder, create a subfolder and name it PrestagedImages.

   Note   This folder must be called PrestagedImages.

3. To apply Access Control Lists (ACL) security to the MED-V Images folder, set the following ACL:

   NT AUTHORITY\Authenticated Users:(OI)(CI)(special access:)

                                        **READ\_CONTROL**
   
                               **SYNCHRONIZE**
   
                               **FILE\_GENERIC\_READ**
   
                               **FILE\_READ\_DATA**
   

   **                                 FILE_APPEND_DATA**

                               **FILE\_READ\_EA**
   
                               **FILE\_READ\_ATTRIBUTES**
   

   NT AUTHORITY\SYSTEM:(OI)(CI)F

   BUILTIN\Administrators:(OI)(CI)F

   Note   It is recommended to apply ACL security to the MED-V Images folder.

4. To apply ACL security to the PrestagedImages folder, set the following ACL:

   NT AUTHORITY\Authenticated Users:(OI)(CI)(special access:)

   READ_CONTROL

   SYNCHRONIZE

   FILE_GENERIC_READ

   FILE_READ_DATA

   FILE_READ_EA

   FILE_READ_ATTRIBUTES

   NT AUTHORITY\SYSTEM:(OI)(CI)F

   BUILTIN\Administrators:(OI)(CI)F

   Note   It is recommended to apply ACL security to the PrestagedImages folder.

5. Push the image files (CKM and INDEX files) to the PrestagedImages folder.

   Note   After the image files have been pushed to the pre-stage folder, it is recommended to run a data integrity check and to mark the files as read-only.

6. Include the following parameter in the MED-V client installation: Client.MSI VMSFOLDER=”C:\MED-V Images”.

How to Update the Pre-stage Location

To update the pre-stage location

1. The registry key, PrestagedImagesPath, points to the default image location. It is located in the following directory:

   • On an x86 - KEY_LOCAL_MACHINE\SOFTWARE\Kidaro

   • On an x64 - HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432node

2. If the image is in a different location, change the path.
