For manual unmanaged pools in View, the View Connection Server instance is not able to obtain information from a vCenter Server instance. The unmanaged machines must therefore be registered with the View Connection Server instance before they can be added to a desktop pool.
The topic Prerequisites for Adding Unmanaged Machines to Pools applies to all types of unmanaged machines. The other topics in this chapter apply only to physical machines that you add to a View desktop pool.
The Add Unmanaged Machines to Pool workflow is available with Horizon vCenter Orchestrator plug-in 1.1.
