Current Series Release Notes

10.0.0.0rc1-220

Default quotas for the following resources were increased: networks (from 10 to 100), subnets (from 10 to 100), ports (from 50 to 500).

New Features

  • Resource tag mechanism now supports subnet, port, subnetpool and router resources.
  • In order to reduce metadata proxy memory footprint, haproxy is now used as a replacement for neutron-ns-metadata-proxy Python implementation.

Upgrade Notes

  • Default quotas were bumped for the following resources: networks (from 10 to 100), subnets (from 10 to 100), ports (from 50 to 500). If you want to stick to old values, consider explicitly setting them in the neutron.conf file.
  • Since haproxy was not used before by neutron-l3-agent and neutron-dhcp-agent, rootwrap filters for both agents have to be copied over when upgrading.
  • To upgrade to the haproxy based metadata proxy, neutron-l3-agent and neutron-dhcp-agent have to be restarted. On startup, old proxy processes will be detected and replaced with haproxy.
  • After upgrade, a macvtap agent without physical_interface_mappings configured can not be started. Specify a valid mapping to be able to start and use the macvtap agent.

Deprecation Notes

  • The gateway_external_network_id L3 agent option is deprecated and will be removed in next releases, with external_network_bridge that it depends on.
  • The of_interface Open vSwitch agent configuration option is deprecated and will be removed in the future. After option removal, the current default driver (native) will be the only supported of_interface driver.
  • The nova_metadata_ip option is deprecated and will be removed in Queens. It is deprecated in favor of the new nova_metadata_host option because it reflects better that the option accepts an IP address and also a DNS name.
