[ovirt-users] Restrict a single storage domain for users/roles

Hello, this is my first message on ML. First off, a short recap: I'm setting up an oVirt test environment based on version 4.1.5.2. Once in production, I'm planning to let users access the dashboard with a custom role for basic operations (like startup, shutdown or creation of VMs). For storage domains I'm using both NFS and Cinder, and I'd like to know if there's a way to limit, for users, creation of new volumes only on Cinder. Best regards, Marco
