[Openstack-operators] Problems with openstack-nova-network-2012.2.2-1 adding floating_ips pools

We've worked with my OpenStack installation for several months and now I 
have to create two pools (public and private pools) of floating_ips.

I noticed that the floating_ip doesn't work correctly:

1)cat /etc/nova/nova.conf | grep public

2) I need to establish the public_interface depending on the pool, so that:
nova-manage floating create --pool=private-ips 
--ip_range=  --interface=eth0
nova-manage floating create --pool=prublic-ips 
--ip_range=  --interface=eth0.4

3) I listed my pools:
nova-manage floating list
2fd8747b4eb64ce4bd7149e2d45ff076    None public-ips    
2fd8747b4eb64ce4bd7149e2d45ff076    None private-ips    

4) I created the IPs from both pools
nova floating-ip-create  private-ips
nova floating-ip-create  prublic-ips

5) I add the IP to some instances ... but I can see that all the 
secondary IPs are created on eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP 
qlen 1000
     link/ether 00:1a:64:5d:60:00 brd ff:ff:ff:ff:ff:ff
     inet scope global eth0
     inet scope global eth0
     inet6 fe80::21a:64ff:fe5d:6000/64 scope link
        valid_lft forever preferred_lft forever

Why all the secondary IPs are created on eth0?  It seems the 
public_interfaces of *"nova-manage floating create*" are *ignored*.

Any help?
