For an example it would probably be useful to use a more traditional
case, i.e. more than one vCPU per vNode.

Also, the settings above say nothing about the relationship to
physical nodes, yet that's an important aspect for VM creation.
Are you perhaps implying that each vNode would get assigned
to a tool stack chosen pNode? What if there are more vNodes
than pNodes? What if node distances vary, and the admin wants
some control over the placement?
