Hey Gianluca, You can use 'hosted-engine' do define your modified config file and once the engine is up and running - it should update the OVF on the shared storage. Also, there is a workaround - you can define the HE manually using virsh , but it requires more work - like creating the vdsm network, create symbolic links on the node you want to power it up, etc. What is the reason behind your will to modify the engine ?
