ovn central #1

Supports: bionic eoan
Add to new model


Principal charm that deploys ovn-northd, the OVN central control daemon,
and ovsdb-server, the Open vSwitch Database (OVSDB).

The ovn-northd daemon is responsible for translating the high-level OVN
configuration into logical configuration consumable by daemons such as

The ovn-northd process talks to OVN Northbound- and Southbound- databases.

The ovsdb-server exposes endpoints over relations implemented by the ovsdb

The charm supports clustering of the OVSDB, you must have a odd number of
units for this to work. Note that write performance decreases as you
increase the number of units.

Running multiple ovn-northd daemons is supported and they will operate in
active/passive mode. The daemon uses a locking feature in the OVSDB to
automatically choose a single active instance.


OVN provides open source network virtualization for Open vSwitch (OVS).
