Ocata Series Release Notes

Ocata Series Release Notes

2.0.0

New Features

  • Initial release of the OpenStack Networking service (neutron) integration with Open Virtual Network (OVN), a component of the Open vSwitch project. OVN provides the following features either via native implementation or conventional agents:

    • Layer-2 (native OVN implementation)
    • Layer-3 (native OVN implementation or conventional layer-3 agent) The native OVN implementation supports distributed routing. However, it currently lacks support for floating IP addresses, NAT, and the metadata proxy.
    • DHCP (native OVN implementation or conventional DHCP agent) The native implementation supports distributed DHCP. However, it currently lacks support for IPv6, internal DNS, and metadata proxy.
    • Metadata (conventional metadata agent)
    • DPDK - Usable with OVS via either the Linux kernel datapath or the DPDK datapath.
    • Trunk driver - Driver to back the neutron’s ‘trunk’ service plugin

    The initial release also supports the following Networking service API extensions:

    • agent
    • Address Scopes *
    • Allowed Address Pairs
    • Auto Allocated Topology Services
    • Availability Zone
    • Default Subnetpools
    • DHCP Agent Scheduler **
    • Distributed Virtual Router *
    • DNS Integration *
    • HA Router extension *
    • L3 Agent Scheduler *
    • Multi Provider Network
    • Network Availability Zone **
    • Network IP Availability
    • Neutron external network
    • Neutron Extra DHCP opts
    • Neutron Extra Route
    • Neutron L3 Configurable external gateway mode *
    • Neutron L3 Router
    • Network MTU
    • Port Binding
    • Port Security
    • Provider Network
    • Quality of Service
    • Quota management support
    • RBAC Policies
    • Resource revision numbers
    • Router Availability Zone *
    • security-group
    • standard-attr-description
    • Subnet Allocation
    • Tag support
    • Time Stamp Fields

    (*) Only applicable if using the conventional layer-3 agent.

    (**) Only applicable if using the conventional DHCP agent.

  • OVN native L3 implementation. The native implementation supports distributed routing for east-west traffic and centralized routing for north-south (floatingip and snat) traffic. Also supported is the Neutron L3 Configurable external gateway mode.
  • OVN native DHCPv6 implementation. The native implementation supports distributed DHCPv6. Support Neutron IPv6 subnet whose “ipv6_address_mode” attribute is None, “dhcpv6_stateless”, or “dhcpv6_stateful”.

Deprecation Notes

  • The ovn group vif_type configuration option is deprecated and will be removed in the next release. The port VIF type is now determined based on the OVN chassis information when the port is bound to a host. [Bug 1606458]
  • The ovn group ovsdb_connection configuration option was deprecated in the Newton release and has now been removed.
