That's interesting, because lack of GARP would not explain that.

I would make sure the VM is functional and that the problem really is the network. Beyond that, we'll have to dig into OVN to figure out what happened. My process would be roughly something like.

1) Checking "ovn-sbctl show" to make sure that the port bindings properly reflect that a port has moved.

2) Assuming #1 is good, I'd be digging into flows to see where my packets are going. Unfortunately, this isn't the easiest thing to do. It's easiest on a system that's otherwise idle, as you can just look at packet counters in the flows and see what's increasing.

A helpful command for watching counters increase: watch -d -n 0.5 "sudo ovs-ofctl -O OpenFlow13 dump-flows br-int | cut -f3- -d','"
