OVN

What is OVN?

OVN (Open Virtual Network) is a series of daemons that translates virtual network configuration into OpenFlow, and installs them into Open vSwitch. It is licensed under the open source Apache 2 license.

OVN is provides a higher-layer abstraction then Open vSwitch, working with logical routers and logical switches, rather than flows. OVN is intended to be used by cloud management software (CMS). For details about the architecture of OVN, see the ovn-architecture manpage. Some high-level features offered by OVN include

  • Distributed virtual routers
  • Distributed logical switches
  • Access Control Lists
  • DHCP
  • DNS server

Like Open vSwitch, OVN is written in platform-independent C. OVN runs entirely in userspace and therefore requires no kernel modules to be installed.

Until recently, OVN code lived within the Open vSwitch codebase. OVN has recently been split into its own repo. There is much to do to complete this split entirely. See the TODO_SPLIT.rst file for a list of known tasks that need to be completed.

What's here?

The main components of this distribution are:

  • ovn-northd, a centralized daemon that translates northbound configuration from a CMS into logical flows for the southbound database.
  • ovn-controller, a daemon that runs on every hypervisor in the cluster. It translates the logical flows in the southbound database into OpenFlow for Open vSwitch. It also handles certain traffic, such as DHCP and DNS.
  • ovn-nbctl, a tool for interfacing with the northbound database.
  • ovn-sbctl, a tool for interfacing with the southbound database.
  • ovn-trace, a debugging utility that allows for tracing of packets through the logical network.
  • Scripts and specs for building RPMs.

What other documentation is available?

To install Open vSwitch on a regular Linux or FreeBSD host, please read the installation guide. For specifics around installation on a specific platform, refer to one of the other installation guides

For answers to common questions, refer to the FAQ.

To learn about some advanced features of the Open vSwitch software switch, read the tutorial.

Each OVN program is accompanied by a manpage. Many of the manpages are customized to your configuration as part of the build process, so we recommend building OVN before reading the manpages.
