And having two VMs would be easier anyways as there are probably other things you'reha going to tune. Yes, I think so. I'm currently working on an OpenStack customer deployment where they want each instance to have an additional NIC for 'management' access into and out from that instance; and there is a correspondingly separate provider network for 'management' purposes between the compute hosts. In general, when an instance has multiple NICs, it needs somehow to arrange that it sets up only one default route, through one of those NICs, and that non-default routes are used to direct traffic to specific destinations through the other NICs.
So people are re-creating their legacy setups, right down to the "iLO management network", sigh :) They do know there is a noVNC answer to get a console:

(FWIW, I also submitted a proposal to talk about this in Barcelona: "Routed (Calico) networking with ECMP, dual fabric planes and data/management separation".)
I'll definitely come and see it if it's accepted Neil. I guess speed designations will be the next thing added to the Network model...
