Hello,
Do what Thomas suggested or disable LLDP because it’s also possible that you are leaking information about your compute node to running instances.
Best regards

I'd suggest adding this to your setup so you're not annoyed anymore:
# cat /etc/lldpd.d/only-eth.conf configure system interface pattern eth*
That's what OCI [1] does by default.
