If you have setup the bridge on the openstack box then do not use the same ip on bridge and on physical NIC network, As a best practice , assign the ip of physical NIC interface to bridge and set the NIC IP to 0. Also check the ip routing table for the default path set on bridge.

ifconfig br-ex x.y.z.a netmask a.b.c.d up
ifconfig eth 0

route -n
the default route should be on br-ex
