You can configure images for Windows guest customization by applying guest customization metadata.

Windows guest customization is an alternative to Cloudbase-Init. Do not use Windows guest customization metadata and Cloudbase-Init on the same image.


  • Install the appropriate version of Microsoft System Preparation (Sysprep) for each guest operating system that you want to customize.
  • Install VMware Tools on the source image.


  1. Log in to the VMware Integrated OpenStack dashboard.
  2. Select your project from the drop-down menu in the title bar.
  3. Select Project > Compute > Images.
  4. Create a new Windows image or choose an existing image to customize.
  5. Select Update Metadata next to the image that you want to use.
  6. In the Available Metadata pane, expand Guest Customization Options.
  7. Click the Add (plus sign) icon next to the metadata that you want to configure.
