We have to prioritize management traffic within controllers and compute nodes.
Bug https://bugs.launchpad.net/mos/+bug/1447619 isn't fully describes the problem because even image transfer from/to glance could be a reason for network disruption.
Basically we need to at least prioritize corosync/pacemaker, rabbitmq and mysql-galera traffic in from of other traffic.
So to implement that we have to do the following:
1. Prioritize traffic on controllers from/to: rabbitmq, corosync/pacemaker, mysql-galera ports.
2. Prioritize traffic on computes to: rabbitmq ports. |

As example we could use -j TOS --set-tos Minimize-Delay for corosync/pacemaker and rabbitmq. Also the same or maximizing throughput(Maximize-Throughput) for mysql-galera. |
