I don't believe most of these things should be configured by commandline 
options. It's only done that way because we don't have any alternative (i.e. a 
machine config file). If you really want full control, I expect your VM 
manager will generate the machine config for you.

Probably identifying things by name.

As I've said before, I think it's good to isolate machine configuration (what 
hardware to emulate) and host configuration (image location, vlans, etc).  The 
details are going to depend how we end up doing the host configuration bits.
