[libvirt-users] libvirt nwfilter

To take advantage of the filters, is it as simple as adding these couple 
of lines in a guest's xml file like the example from 
https://libvirt.org/formatnwfilter.html#nwfconcepts ?

<devices>
     <interface type='bridge'>
       <mac address='00:16:3e:5d:c7:9e'/>
       <filterref filter='clean-traffic'>
         <parameter name='IP' value='10.0.0.1'/>
       </filterref>
     </interface>
   </devices>

Can multiple filters be combined together like this?

<filterref filter='clean-traffic' filter='no-ip-multicast'>
    <parameter name='IP' value='10.0.0.1'/>
</filterref>

Can the IP address parameter override the one in /etc/network/interfaces 
on the guest?

When cloning a vm does it change the ip to avoid conflicts like it would 
with mac-addresses?
