v1.1.0 - 05 Apr 2011
------------------------
- Ability to define policies over IPv6
- LACP
- 802.1ag CCM
- Support for extensible match extensions to OpenFlow
- QoS:
- Support for HFSC qdisc.
- Queue used by in-band control can now be configured.
- Kernel:
- Kernel<->userspace interface has been reworked and should be
close to a stable ABI now.
- "Port group" concept has been dropped.
- GRE over IPSEC tunnels
- Bonding:
- New active backup bonding mode.
- New L4 hashing support when LACP is enabled.
- Source MAC hash now includes VLAN field also.
- miimon support.
- Greatly improved handling of large flow tables
- ovs-dpctl:
- "show" command now prints full vport configuration.
- "dump-groups" command removed since kernel support for
port groups was dropped.
- ovs-vsctl:
- New commands for working with the new Managers table.
- "list" command enhanced with new formatting options and --columns
option.
- "get" command now accepts new --id option.
- New "find" command.
- ovs-ofctl:
- New "queue-stats" command for printing queue stats.
- New commands "replace-flows" and "diff-flows".
- Commands to add and remove flows can now read from files.
- New --flow-format option to enable or disable NXM.
- New --more option to increase OpenFlow message verbosity.
- Removed "tun-cookie" command, which is no longer useful.
- ovs-controller enhancements for testing various features.
- New ovs-vlan-test command for testing for Linux kernel driver VLAN
bugs. New ovs-vlan-bug-workaround command for enabling and
disabling a workaround for these driver bugs.
- OpenFlow support:
- "Resubmit" actions now update flow statistics.
- New "register" extension for use in matching and actions, via NXM.
- New "multipath" experimental action extension.
- New support for matching multicast Ethernet frames, via NXM.
- New extension for OpenFlow vendor error codes.
- New extension to set the QoS output queue without actually
sending to an output port.
- Open vSwitch now reports a single flow table, instead of
separate hash and wildcard tables. This better models the
current implementation.
- New experimental "note" action.
- New "ofproto/trace" ovs-appctl command and associated utilities
to ease debugging complex flow tables.
- Database:
- Schema documentation now includes an entity-relationship diagram.
- The database is now garbage collected. In most tables,
unreferenced rows will be deleted automatically.
- Many tables now include statistics updated periodically by
ovs-vswitchd or ovsdb-server.
- Every table now has an "external-ids" column for use by OVS
integrators.
- There is no default controller anymore. Each bridge must have its
controller individually specified.
- The "fail-mode" is now a property of a Bridge instead of a Controller.
- New versioning and checksum features.
- New Managers table and manager_options column in Open_vSwitch table
for specifying managers. The old "managers" column in the
Open_vSwitch table has been removed.
- Many "name" columns are now immutable.
- Feature removals:
- Dropped support for XenServer pre-5.6.100.
- Dropped support for Linux pre-2.6.18.
- Dropped controller discovery support.
- Dropped "ovs-ofctl status" and the OpenFlow extension that it used.
Statistics reporting in the database is a rough equivalent.
- Dropped the "corekeeper" package (now separate, at
http://openvswitch.org/cgi-bin/gitweb.cgi?p=corekeeper).
