Hello,
I have VM attached to bridge br0. VM can see the network (ping works) when
the bridge has ethernet interfaces. But when I create bond or team device
and attach it to a bridge instead of eth interface, VM does not ping
anymore. Any ideas why?
Thanks,
Nerijus
Hi Nerijus,
the chances are that your ethernet packets are “looping" through physical switches
and that they are overwriting the forwarding table of your software bridge.
Try to dump the forwarding table (watch -n1 brctl showmacs <brname>). If you see
your VM mac address changes port over time, you are hitting that issue.
In that case, the following could help to fix that issue.
