Each part of the schema should have docs describing what CLI args it
corresponds to. eg document that when device=memory, corresponds
to -bios, that device=flash, corresponds to -drive if=pflash, etc

We've not trying to replace the cmdline generator in libvirt. We just
want to know that when we see a particular field present in the schema,
that it corresponds to a particular cli arg.

Daniel
