You can create a pool of desktop machines by cloning a vCenter Server virtual machine (VM). Before you create the desktop pool, you need to prepare and configure this VM, which will be the golden image of the clones.
For information about preparing machines that are used as Remote Desktop Services (RDS) hosts, see the Setting Up Published Desktops and Applications in Horizon Console guide.
For information about preparing Linux VMs for remote desktop deployment, see the Setting Up Horizon 7 for Linux Desktops guide.
