So, I have this deployment. All baremetal hosts (with the unique exception of Director being a virtual guest). 

So, make my custom nics and custom network and custom roles and custom ... you get it. I try to tell the controllers that they're ControllerStorageNfs so that they can use an external Ceph 5 cluster. (I use Train, btw). 

In any case, when I try to deploy my 3 controllers and 3 computes, the computes end up with linux_bond everywhere (which is my intention) and the controllers end up with ovs (which isn't my intention). 

I dunno why. I'd appreciate pointers if possible. I'm all confused. I dunno what to paste in order to tell you what the problem is... :s
