Description of problem:
splat has a SNO cluster that we need to configure a bridge on. I unknowingly added a new bridge without adding a ovs bridge mapping which caused cluster networking to fail.
The bridge mapping within OVS was set to ":,"
[root@a9 ~]# sudo ovs-vsctl get Open_vSwitch . external_ids
{hostname=a9.c4.3ba9.ip4.static.sl-reverse.com, ovn-bridge-mappings=":,physnet:br-ex",ovn-enable-lflow-cache="true", ovn-encap-ip="169.59.196.169", ovn-encap-type=geneve, ovn-is-interconn="true", ovn-memlimit-lflow-cache-kb="1048576", ovn-monitor-all="true", ovn-ofctrl-wait-before-clear="0", ovn-openflow-probe-interval="180", ovn-remote="unix:/var/run/ovn/ovnsb_db.sock", ovn-remote-probe-interval="180000", ovn-set-local-ip="true", rundir="/var/run/openvswitch", system-id="53cb5a29-1f91-402e-b7dc-650715c7d30d"}
[root@a9 NetworkManager]# nmstatectl show --json [2025-05-21T19:30:13Z INFO nmstatectl] Nmstate version: 2.2.40 NmstateError: InvalidArgument: Cannot convert : to OvnBridgeMapping, expected format is `<localnet>:<bridge>` [root@a9 NetworkManager]#
Version-Release number of selected component (if applicable):{code:none}
How reproducible: I am assuming always
Steps to Reproduce:{code:none}
1. Create NNCP policy with UI and empty OVN localnet, and OVS bridge name
Actual results:
Expected results: validation that stops the creation of an empty bridge mapping
Additional info:{code:none}
