Before you can start delivering session-based desktops or remote applications to your end users from your deployed node, you must create at least one assignable desktop image. Creating this assignable image is a multi-step process: a master virtual machine (VM) must be created, then customized according to your organization's needs, and then converted into an assignable desktop image.
First, you use the Import Desktop wizard's option to create the master virtual machine (VM) using one of the supported VM configurations from the Microsoft Azure Marketplace. Using the wizard automates building the master virtual machine (VM) and configuring the VM to conform to the Horizon Cloud environment's requirements, including installing the required agents. From the Inventory page, start the Import Desktop wizard by clicking Import and then select the From Marketplace option. For steps, see Create a Master Virtual Machine from the Microsoft Azure Marketplace.
When the master VM is visible on the Imported VMs page and the page indicates the DaaS agent is active, then you customize the master VM's guest Windows Server operating system (OS) with the third-party applications you want to provide to your end users, as well as configure any OS-level settings such as customized wallpaper, fonts and colors, drivers, and other such items. For steps, see Customize the Guest Windows Operating System of the Master Image Virtual Machine, Install NVIDIA Graphics Drivers in an NV6 Server Model Master Image, and Install the User Environment Manager Agent in the Master Image Virtual Machine.
Then you use the New Image workflow in the Administration Console to convert that master VM to an assignable desktop image. For steps, see Convert a Configured Master Virtual Machine to an Assignable Image.
After the master VM is converted, you can create an RDSH farm based on that image when you see that the image on the Inventory - Images page displays the Published status. The Published status indicates Horizon Cloud has sealed the image VM for use in the Horizon Cloud environment.
You can create both types of farms from the same published RDS image: desktop farms to provide session-based desktops and application farms to provide remote applications. When you have a farm, you can use it to make assignments to users. See Farms in Horizon Cloud.
