There needs to be an explicit way using one of the tools to say 'Don't install anything on this, just build an xml file with these options'. In turn there could be a flag to dump out libvirt xml or virt-image xml. The main problem is, where do we do this? - virt-install: Seems the only option for libvirt xml, if we want to define and start the guest. But what about just dumping out the xml? Seems like it may be getting a bit too ambitious. There are lots of virt-install options that don't map well to virt-image, though we could just build the xml and feed it through a libvirt xml -> virt-image parser in virt-convert. - virt-image: no go for libvirt xml, but could be expanded to build image xml, and probably the most consistent place to do it. - separate tool, something like virt-import? would duplicate all the option parsing, but probably the cleanest solution. I'd have to look at it all a bit more and determine what it would really require to build up virt-image xml and how the options would differ from a subset of virt-install options to make an informed decision.
