The OS layer is a virtual disk attached to a virtual machine running the supported Windows Operating System that you want to use for your Layered Images.
This topic explains how to prepare a clean OS image for layering, and then import the image into a new OS layer. Once created, you can use the OS layer to build as many App layers, Platform layers, and Layered Images as you need.
Once you have completed these steps, you are ready to create an OS Layer.
In the Management Console, select Layers > OS Layers and click Create OS Layer in the Action bar. This opens the Create Operating System Layer Wizard.
In the Layer Details tab, specify a Layer Name and Version, both required values. Optionally, you can enter Descriptions of the Layer and Version, and change the Max Layer Size to accommodate the OS you are going to import. For details, see more about these values below.
In the Connector tab, choose a Connector Configuration for the platform where you'll be publishing your Layered Images. If the configuration you need is not listed, add a New one and select it from this list. For information about creating a new Connector Configuration, see Create a Connector Configuration.
Note: Alternatively, if you have a *.vhd file of the OS disk in your File Share, you can select the file share instead of an App Layering connector.
In the Import Disk Details tab, enter the name of the Azure Resource Group that contains the OS disk and the name of the OS disk, both required values.
If you specified a file share on the Connector tab, enter the name of the OS disk residing on that file share or click Browse to select it.
In the Icon Assignment tab, select an icon image to assign to this layer.
In the Confirm and Complete tab, review the details of the OS Layer, enter a comment if required, and click Create Layer. If you enter comments, they appear in the Information view Audit History.
When the task completes, the new OS Layer in the Management Console displays a "Deployable" status.
