You can manage desktop managers on the Desktop Managers page.

A desktop manager is a per-tenant resource that manages each tenant's virtualization resources and communicates with a tenant's compute resources (hypervisors). Each desktop manager needs to be associated with a resource manager and one or more host managers.

When you click on the Desktop Managers panel on the left side of the Resources screen, the right side of the Resources screen displays the General tab. The General tab lists the assigned Desktop Managers and unassigned Desktop Managers. You can assign an unassigned Desktop Manager from this tab as well as unassign one that is already assigned.

When you select the link for a specific Desktop Manager, the General tab shows the Name, Id, Tenant, and Resource Manager for that Desktop Manager, and the panel updates to display additional tabs: Compute Resources, Instances, Networks, and Datastores.
