How to Configure Image Prestaging

  • Article

Note

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

To configure image prestaging

  1. On the client computer, under the image store directory, create a folder for the prestaging 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's 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_APPEND_DATA
    • FILE_READ_EA
    • FILE_READ_ATTRIBUTES
    • NT AUTHORITY\SYSTEM:(OI)(CI)F
    • BUILTIN\Administrators:(OI)(CI)F

    Note

    It's 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 prestage location

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

    • On an x86 - HKEY_LOCAL_MACHINE\SOFTWARE\Kidaro

    • On an x64 - HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432node

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