The Abiquo UI can display groups of regions or specific regions when allowing tenants access to a provider, and when creating, editing, or viewing scopes.
To configure this feature, set the "config.enterprise.onlyuseproviders property" to true. See Configure Abiquo UI.
When allowing access to a provider, Administrators can allow all of its regions or selected regions.
To create allocation limits for a provider or an endpoint (vCloud and OpenStack), edit the allowed provider and go to Allocation limits.
At this level you can also set a default role for VDCs. And you can create a scope for administrators to manage all regions in a provider or selected regions.
You can also display the regions grouped by provider when displaying scopes.
