I don't understand why do you use 2 bridges br-ex and br-ex.30.
Considering that you have ip 192.168.2.19 configured on ifcfg-eth0.30 you
should use br-ex:eth0.30 mapping
Can you show interfaces configuration?
#ifconfig
And bridge_mappings
on /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini?
Thanks
