[Openstack] Security Groups rules applied but ignored...

Guys,

I'm back using "libvirt_vif_driver =
nova.virt.libvirt.vif.LibvirtHybridOVSBridgeDriver" (nova-compute.conf) but
the problem persist for "tenant1".

My nova.conf contains:

---
# Network settings
network_api_class = nova.network.neutronv2.api.API
neutron_url = http://contrller-1.mydomain.com:9696
neutron_auth_strategy = keystone
neutron_admin_tenant_name = service
neutron_admin_username = neutron
neutron_admin_password = 123test123
neutron_admin_auth_url = http://controller-1.mydomain.com:35357/v2.0

linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver

# If you want Neutron + Nova Security groups
firewall_driver = nova.virt.firewall.NoopFirewallDriver
security_group_api = neutron
---

Is that a valid configuration for Havana?! I'm get it from my previous
Grizzly setup.

Also, I just realized that, there are two places to configure the
"firewall_driver", first one is located at nova.conf, the second is located
at "ovs_neutron_plugin.ini" under [securitygroups], of course, I believe,
they must "match", I mean, I must be the same for both services, right?!

Thanks!
Thiago
