vm with multiples user-defined fixed-ips not supported by quantumv2 driver

[Cedric Brandily]

QuantumV2 driver does not support correctly the instantiation of a virtual machine having multiples interfaces with user-defined fixed-ips.
It could be highlighted by doing something like:
 nova boot .... vm --nic net-id=$uuid1,v4-fixed-ip=$ip_onuuid1_subnet --nic net-id=$uuid2,v4-fixed-ip=$ip_on_uuid2_subnet

The trouble comes from the fact that quantumV2 driver for every interface with user-defined fixed-ips uses the last fixed-ip.
So when you try to create the first vm interface, the driver use the last fixed-ip.

In attachment i provide the patch to correct the bug !

It affects folsom stable and grizzly trunk nova quantum driver

    Fix multiple fixed-ips with quantum.

    This patch fixes a bug in the quantum suppot where multiple requested
    fixed-ips did not work. Every network interface would be given the last
    fixed IP that was specified. The problem was just the lack of putting
    the right fixed ip in a local variable.

    Fix bug 1154093.
