Right now, ovn-controller implies unix: connection scheme. It may be helpful to connect to vswitchd via a proper AF_INET socket, to e.g. avoid file system sharing in cloud-native environments. (The assumption is that these sockets would then be secured by SSL certificates.)

The relevant code section demonstrating the assumption:

ofctrl_run(const struct ovsrec_bridge *br_int,
const struct ovsrec_open_vswitch_table *ovs_table,
struct shash *pending_ct_zones)
{
char *target = xasprintf("unix:%s/%s.mgmt", ovs_rundir(), br_int->name);
bool reconnected = false;
if (strcmp(target, rconn_get_target(swconn)))
{ VLOG_INFO("%s: connecting to switch", target); rconn_connect(swconn, target, target); }
 

AFAIU as part of this feature support, connection probing should be enabled for the AF_INET sockets.
