Hi Syd,

Are you trying comput nodes [heterogeneous or Homogeneous] multi-node
setup. Based on our experience with Multi-Node setup [homogeneous], Only
for developer/tester understanding we need gateway IP interface on the
controller to reach VMs on compute nodes.

In real time deployment, Controller will not have any control on Compute
Nodes or VMs in Comput Nodes. Controller is only for controlling the VMs
creation/deletion etc. On networking front, controller will not have any
control over VMs created in Compute nodes.
