can you post your libvirt xml for the VM? It maybe well be libvirt
filtering if you are using the OVS Hybrid vif driver:
for example, a VM would have xml like:
<filterref filter='nova-instance-instance-00000001-fa163e0569ba'>
<parameter name='DHCPSERVER' value='10.0.0.2'/>
<parameter name='IP' value='10.0.0.3'/>
<parameter name='PROJMASK' value='255.255.0.0'/>
<parameter name='PROJNET' value='10.0.0.0'/>
</filterref>
I'm not sure what the nova code would generate for multiple IPs.
