This one would be confused with macvtap in bridge mode (which is 
recognized by mode='bridge' and the presence of a dev attribute (or 
rather, an array of <interface> elements being present, of which by 
definition the first is copied into the dev attribute for historical 
reasons).

A human might confuse that one with a host bridge network (which is the 
same, except the <bridge> element isn't inside the <forward> element).

I'm leaning towards:

<network>
<name>ovs-network</name>
<forward mode='bridge'/>
<bridge name='ovs-bridge' type='openvswitch'/>
</network>
