Description of problem: After update to use nmstate source routes the code won't create a new source route unless the config has changed. This however might not be the case if the routes for example removed externally, in that case the network configuration would stay the same but the route is missing. That causes out-of-sync on engine that cannot be fixed by simple network synchronization. Version-Release number of selected component (if applicable): vdsm-4.40.80.6-1.el8ev.x86_64 How reproducible: 100% Steps to Reproduce: 1. Setup network with custom gateway (static/dynamic) that is not default route 2. Remove the source route from host 3. try to synchronize the network on the host Actual results: Engine shows the network is still out-of-sync, missing the gateway Expected results: It should be synchronized Additional info: There are two possible workarounds: 1) Change or remove the gateway of affected network, apply the configuration to the host and then apply the configuration again with the gateway back. 2) Remove /var/lib/vdsm/staging/netconf/nets/$NET_NAME on the host and then run network synchronization from engine
One small thing to note, this does not apply to networks that have default route role.
Verified on - vdsm-4.40.100.1-1.el8ev.x86_64 with rhvm-4.4.10-0.17.el8ev.noarch
