The existing forward mode bridge could also work perhaps. If there are no

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).



Or maybe the real syntax is,

<network>
     <name>ovs-network</name>
     <forward mode='bridge'>
         <bridge name='ovs-bridge'/>
         <script path='/etc/qemu-ifup-ovs'/>
     </forward>
</network>


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>
