[Users] does engine require connectivity to ovirtmgmt interface

Hi all, Is connectivity between engine and the ovirtmgmt interface required? I have currently a strange setup where the engine is in another network then the host. Connectivity is from engine to host only (and a few ssh tunnels). Like this I can't see any disks (but I can create new ones) and also I can't see any hosts from the networks tab. Everything else seems to work: create/start VM, start spice agent, etc. There is nothing in the logs to alert me of any errors. Best regards, Cristian Falcas
