Hi Folks, Apologies if this is a dumb question I'm not too familiar with the what goes on between ovn-controller and the kernel OVS flows.
So ovn-controller is control plane, the OVS flows it get pushed down to the kernel (the data plane). So I expected that if ovn-controller is stopped on a hypervisor that the dataplane flows would persist in the kernel. But what I see is if I have a VM on hypervisor A and a gateway on hypervisor B. If I stop ovn-controller on hypervisor A then I can no longer access the VM via the gateway. There is no Geneve traffic sent to hypervisor A. I guess as expected CENTRAL has taken hypervisor A out of the Southbound DB, regenerated flows and updated hypervisor B. I thought that the OVS flows might persist in the kernel in hypervisor A and CENTRAL would use the last known location of the VM and not regenerate flows and still tunnel from the gateway on B to A. But I guess not, but it does seem odd that the control plane going down breaks the data plane.
