oVirt by default works in bridge mode.
This means that is going to create a bridge on your hosts and the vnic of
your VMs will be connected to that bridge as well.

oVirt is composed by a central engine managing physical hosts trough an
agent deployed on each host.
So the engine has to be able to reach the managed hosts, this happens
though what we call management network.

hosted-engine is special deployment where for ha reasons the oVirt engine
is going to run on a VM hosted on the host that it's managing.
So, wrapping up, with hosted-engine setup you are going to create a VM for
the engine, the engine VM will have a nic on the management network and
this mean that you have a management bridge on your host.
The host has to have an address over the management network in order to
have the engine able to reach your host.

That's why hosted-engine-setup is checking the address of the interface you
choose for the management network.
