If that's your only interface, there is no need to specify anything in localrc. I rarely do that, but if you wish to use flat or vlan networking you'll probably need to specify the name of a bridge in localrc. > > Once I have a working OpenStack, the remaining questions are about how to > use it to create a VM with the desired ability.

Any tricks missed here? > Devstack will give you a private network connected to a router which is uplinked to the external network. So you're right - you just need to boot a vm and assign a floating ip to its port. > Does it matter whether my machine at 10.84.133.238 is a bare metal machine > or a VM in some undercloud? > I don't think it matters, at least with the ML2 plugin and OVS/LB mech drivers - plus other plugins I know of.
