Hi Alex,

The 'base' is a VM on VMWare btw, maybe that has something to do with
the weird behaviour?
[root@base ~]# ovs-ofctl show br-inet

I hadn't seen the output of ovs-ofctl show before, but now that I
have, and since it's the VMware VM's uplink, my suspicion is the VM is
seeing frames arrive back in on ens224 with a src mac of the LXC
container, the port id is flapping.
If you have any further suggestions let me know - otherwise I'll do
more capturing on the ens224 side and see what I find.
Thanks,
Chris
