Before you can start assigning virtual desktops to your end users, you must create a desktop image that the system can use to spin out the virtual desktops. Creating a desktop image is a multi-step process.
First build a master virtual machine (VM), which includes several tasks to produce a master virtual machine that conforms to the Horizon Cloud environment's requirements.
Then copy this configured master VM to the file system that is joined to your Horizon Cloud Node and import it into the environment using the Import button on the Locations - File Shares page.
Use the New Image workflow in the Administration Console to convert the imported master virtual machine to a desktop image.
When the image on the Inventory - Images page displays the Published status, indicating it is ready for use, the system can use it in desktop assignments. At that point, you can assign the desktop image to end users. See Create a Dedicated or Floating Desktop Assignment.
