The libvirt driver provides port filtering capability. This capability is enabled when the following is true: - The IPTables firewall driver is enabled - Security groups are disabled - Neutron port filtering is disabled - An IPTables-compatible interface is used, e.g. hybrid mode, where the VIF is a tap device When enabled, libvirt applies IPTables rules that provide MAC, IP, and ARP spoofing protection. At present, setting the 'use_ipv6' config option to False prevents the generation of IPv6 rules even when there are IPv6 subnets available. This is fine when using nova-network, where the same config option is used to control generation of these subnets. However, a mismatch between this nova option and equivalent IPv6 options in neutron would result in IPv6 packets being dropped. Seeing as there is no apparent reason for not allowing IPv6 traffic when the network is IPv6-capable, we can ignore this option. Instead, we use the availability of IPv6-capable subnets as an indicator that IPv6 rules should be added. This paves the way for deprecating the 'use_ipv6' option, which is now only used for two deprecated features: nova-network and file injection.
