Dear list, I just discovered the hard way that if the lower lever physical interface of a macvlan bridge is disconnected (ie: by unplugging the eth cable, resulting in no carrier), inter-guest network traffic from all virtual machines bound to the disconnected interface is dropped.
This behavior surprises me, as with the classic bridges I can disconnect the underlying physical interface without causing any harm to inter-guest traffic.
Am I doing something wrong, or this really is the expected behavior? If so, can I force the macvtap interfaces to bridge traffic even when the underlying physical interface is disconnected?
Can you share the <interface> configuration for your guest NIC so we can see how it is setup.
