Hi Alex/List,
Any further ideas on troubleshooting this?
I can fix it by adding some network noise to rc.local but that seems
kinda hacky.
Is there a way to debug what frames are causing insert or updates to
fdb entries to see why this might be happening?
Regards,
Chris

Hi Krist,
I started a thread a few days ago with subject:
LXC, OVS and fdb learning problem
Your symptoms sound very similar to what I'm seeing. I havn't resolved my
symptoms yet unfortunately :(
I'm running my LXC base & container on top of VMware ESX, and thus my vSwitch

I've been using the kernel version provided with CentOS7 with OVS

The 'base' is a VM on VMWare btw, maybe that has something to do with
the weird behaviour?

Thanks for the reply.
It's centos kernel & in-kernel openvswitch module, and userspace is

I would have thought so too.
Here's some detailed info I'm capturing to show working/non-working:

Hi there,
I've setup LXC with OVS on CentOS7 yesterday and am having problems with
OVS learning the MAC address of a container.
I am only seeing ovs-appctl fdb/show reporting the correct port
id for the container mac address when the container generates an ARP
reply, either in response to an ARP
10 matches
