Instance creation with Local network failed when using ML2 linuxbridge mechanism driver

Hi All

i am working with Juno (2014.2.3) both controller and compute

the compute neutron ml2 mechanism driver is set to linuxbridge

(when working with openvswitch mechanism driver all works fine)

what happen is that if failed to launch instance with local network not as first nor last one we

for example

First NET is Vlan  , Second NET is Local , Third  NET is Vlan  - failed 
First NET is Local , Second NET is Vlan  , Third  NET is Vlan  - pass
First NET is Vlan  , Second NET is Vlan  , Third  NET is Local - pass

failure log error is

device tap82788db3-56 is already enslave it to bridge brqb6a9480f-cd

Is this known bug ? Any fix or workaround ? (beside reordering the networks at the instantiation request )

thanks in advance

what happen is that if failed it success to launch instance with local network not as first nor last one we

(when working with openvswitch mechanism driver all works fine)

for example

however the taps is assoicated with qbr### type of bridge instead of brq### one

the brq### bridge created with no associated ports

so if i make two VMs with same local network i am expecting to get

First NET is Vlan tapX -- brq  , Second NET is Local , Third  NET is Vlan  - failed 
First NET is Local , Second NET is Vlan  , Third  NET is Vlan  - pass
First NET is Vlan  , Second NET is Vlan  , Third  NET is Local - pass
-- tapY

failure log error is instead i get

tapX -- qbrX 
tapY -- qbrY
brq### without any ports

btw, other networks of type vlan or flat are made only with brq### bridge , as expected

of course after i get errors that are sympthom of this such as

device tap82788db3-56 is already enslave it to bridge brqb6a9480f-cd

Is this known bug ? Any fix or workaround any way to avoid making the qbr bridges ? (beside reordering the networks at the instantiation request )and just associating two taps to same bridge in order to chain VMs ?

thanks in advance
