Running a GUI on these machines is not possible - the OS is stripped
down enough that there's no support for it.
To be clear - this current config works - when I hit the VIP it flips
between the endpoints. It just doesn't work for traffic from a docker
container, which crossses a linux bridge and is seen as "routed"
traffic as opposed to local.
I want to avoid encapsulating, if i can - many of the systems we're
building on are already running an encap like VXLAN, and the cost is
already too high.
