I'm just wondering if we should consider to switch to the "VM-like"
docker (v.1.10) centos/ubuntu based containers plus pipework [0] for
advanced networking? Yes, this'd be not a "docker way", but containers
provide less overhead to HW infra and are really lightweight comparing
to VMs!

Sorry, it that was an off-topic/irrelevant... But I have a simple PoC
example [1] that proves that it works more or less, at least for me,
well - it tests a rabbitmq cluster built on top of a pacemaker cluster
in docker containers at Travis CI. No nodepools, and only VM's involved
is the one that Travis spawns for a user's job.
