Marcus, I have not set any specific traffic labels/network bridge and let the cloud stack create the default network labels.

What do you see in ls /sys/devices/virtual/net? What is your advanced network config (which physical devices, which bridges, which traffic labels are set for which traffic types)? It looks like it's not finding the parent eth/bond device of the bridge you specified via traffic label.
