This module generates systemd service files for OVN and the OVS services needed by OVN. The systemd service files are heavily based on those provided by the Debian package ([Debian source for OVN])(https://sources.debian.org/src/ovn).
You can simply copy the three .nix files into the same directory as your configuration.nix and then import ./ovn.nix in your configuration.nix.
ovn.nix imports ovn-host.nix and ovn-central.nix, and activates their services using the services.ovn-*.enable options.
You can also modify ovn.nix to pass options to these services by setting services.ovn-*.ovn_ctl_opts, as you would have on Debian by setting the OVN_CTL_OPTS environment variable in /etc/default/ovn-*
You need to change the network.ovs.connection server configuration option in Incus for it to find the OVS database.
If you did not set services.ovn-*.ovn_ctl_opts, you will have a standalone OVN installation with an OVS server listening at /usr/local/var/run/openvswitch/db.sock, therefore you need to set the option as follows:
network.ovs.connection: unix:/usr/local/var/run/openvswitch/db.sock
- At shutdown incus stop command timeouts after 10 minutes.
