RHEV-H or RHEL hosts can be installed using traditional methods either interactively (from ISO, USB flash media) or automated (PXE). There is however no integrated capability to deploy RHEV centrally to bare metal hosts using the RHEV management.

This is possible using Satellite 6 using Foreman. RHEV allows bare metal provisioning via Satellite in a single UI.
