So I'm not generally opposed to this idea, however the way this patch
implements it is a massive duplication of the virtinst apis, so
NACK in this current form.

Like Dan mentioned before, if we allow converting to libvirt xml, we
need to make it clear that the generated config is really only
applicable on the machine it is generated. A connection must be
required in order to do the conversion so we can use the virtinst
apis and check capabilities xml. This makes it kind of messy since
we will have cli options that are relevant for some formats and
not for others, but it's unavoidable, and as long as the
documentation is clear, it shouldn't be confusing.

Thanks,
Cole
