How about this????
in plugin.ini set like this
bridge_mappings = Physnet1:br-ex1,Physnet2:br-ex2

then go on and create a proxy bridge to emulate two network on same nic
ovs-vsctl add-br br-proxy
ovs-vsctl add-port br-proxy ethx

ovs-vsctl add-br br-ex1
ip link add name ex1-br-proxy type veth peer name proxy-br-ex1
ovs-vsctl add-port br-ex1 ex1-br-proxy
ovs-vsctl add-port br-proxy proxy-br-ex1

ovs-vsctl add-br br-ex2
ip link add name ex2-br-proxy type veth peer name proxy-br-ex2
ovs-vsctl add-port br-ex2 ex2-br-proxy
ovs-vsctl add-port br-proxy proxy-br-ex2

I am sorry but I still did not give you multiple flat networks on same physical network.
However now you have two flat physical networks both bridged to same nic.

If anyone got better suggestion please reply..

Thank you,

Subject: [Openstack] Multiple Flat Networks same physical net

Hello
        i have a use case where i have to use two provider networks over the
same physical nic.

My provider provides me 2 network ranges (each has it's netmask and
gateway) over the same nic. without VLAN or tunneling.
 i need to expose both network ranges to the VMs

my initial tough was to create 2 provider networks each one with it's
own subnet, then setup 2 vNIC in each vm

$ neutron net-create prov-1 --provider:network_type flat
--provider:physical_network physnet1 --router:external=True

$ neutron subnet-create --allocation-pool
start=192.168.255.151,end=192.168.255.200 prov-1 192.168.255.0/24
--name=prov-1

$ neutron net-create prov-2 --provider:network_type flat
--provider:physical_network physnet1 --router:external=True

then i get this error msg

409-{u'NeutronError': {u'message': u'Unable to create the flat network.
Physical network physnet1 is in use.', u'type': u'FlatNetworkInUse',
u'detail': u''}}


this is kinda expected, flat network does not provide any kind of
isolation, but is a use case in the openstack manuals

http://docs.openstack.org/havana/install-guide/install/zypper/content/section_use-cases-multi-flat.html

anybody has an idea how to implement it?


thanks!

PS: floatip is not an option :(
