If connection_type is None, the default firewall driver should not be nova.virt.libvirt.firewall.IptablesFirewallDriver; it should either be None or the base one. If this fix gets through, devstack needs to be fixed accordingly. See review below for details. https://review.openstack.org/#change,3576 Change-Id: I58dabc50be2d5cdcd509b2ac89a5bd0f78251bd0
