In the past half year, I had 2 network issues, both related to e1000 kernel module, which means I'd lost "just" remote control, messages network (DNS, MQ), storage network (Ceph) and tunnel interface network (Neutron + GRE). I've bought more 4 NICs, and I'll move from 2 isolated NICs (em1 and p5p1) to a single LAG.
