Red Hat Summit第1章 Open Virtual Network (OVN)
Open Virtual Network (OVN) is an Open vSwitch-based software-defined networking (SDN) solution for supplying network services to instances. OVN provides platform-agnostic support for the full OpenStack Networking API. OVN allows you to programmatically connect groups of guest instances into private L2 and L3 networks. OVN uses a standard approach to virtual networking that is capable of extending to other Red Hat platforms and solutions.
This release of the Red Hat OpenStack Platform (RHOSP) does not provide a supported migration from the ML2/OVS mechanism driver to the ML2/OVN mechanism driver. This RHPOSP release does not support the OpenStack community migration strategy. Migration support is planned for a future RHOSP release.
The minimum Open vSwitch (OVS) version required is OVS 2.9.
OVN uses Python 3.6 packages by default.
This section describes the steps required to deploy OVN using director.
OVN is supported only in an HA environment. We recommend that you deploy OVN with distributed virtual routing (DVR).
1.1. Quick Steps: Deploying Containerized OVN on the overcloud
If you are already familiar with OVN, you can use this quick step to deploy OVN with DVR in an HA configuration on the overcloud:
openstack overcloud deploy \
--templates /usr/share/openstack-tripleo-heat-templates \
...
-e /usr/share/openstack-tripleo-heat-templates/environments/services/neutron-ovn-dvr-ha.yaml
....
$ openstack overcloud deploy \
--templates /usr/share/openstack-tripleo-heat-templates \
...
-e /usr/share/openstack-tripleo-heat-templates/environments/services/neutron-ovn-dvr-ha.yaml
....
