Hello Simon,
i am new with oVirt, but are you sure, that this is the way for the self-hosted-engine? Because i have no commands with hosted-***. As far as i understand the engine runs in self-hosted-engine on same host and therefore there is no way to enter the vm with engine and set it to maintenance mode.?! If you have only one host and it sounds like it then upgrading is a bit different. hosted-engine command is available on the HOST. Just shutdown all VM's, either way will work if you have ovirt-guest-agent running inside the VM's
