Only via the oVirt web admin interface. You first add a standard storage
domain, wait for a VM that represents the engine to appear (name:
HostedEngine) and then you can add an additional host with hosted engine
bits directly from the webadmin UI (HostedEngine side tab of Add new host
dialog, select Deploy).

Best regards
