Please check https://www.ovirt.org/documentation/how-to/hosted-engine/ .

That's not enough, you need also 'engine-setup'. But please check the howto.

I strongly suggest to try these things on a test system (can be nested-kvm

if downtime is critical. That's true for anything you do on production, not
only oVirt- or hosted-engine-related stuff.
