The ovn-chassis snap provides Open vSwitch (OVS) and the Open Virtual Network (OVN) distributed controller. Together they form the data plane components of OVN.
Open vSwitch is a multilayer software switch. OVS's goal is to implement a production quality switch platform that supports standard management interfaces and opens the forwarding functions to programmatic extension and control.
OVN, the Open Virtual Network, is a system to support virtual network abstraction. OVN complements the existing capabilities of OVS to add native support for virtual network abstractions, such as virtual L2 and L3 overlays and security groups.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install ovn-chassis, simply use the following command:
sudo snap install ovn-chassis
Browse and find snaps from the convenience of your desktop using the snap store snap.
