Yes, they are very different formats; libvirt XML[1] is geared towards
creating a VM on a specific host/hypervisor. The virt-image XML[2] is
focussed on describing a VM image in a way that can be used to run that
image on a variety of hypervisors.

The conversion from virt-image XML to VMWare should be in virt-convert
(if it's not, that's where it should go)

The virt-convert code for handling virt-image files does look a little
strange .. rather than filling in fixed XML templates, it would be much
cleaner to add toXML methods to the various classes in ImageParser so
that you can just call Image.toXML and get an XML representation of the
internal objects.

That seems like the right approach, but it requires that you add toXML
or similar methods to all the classes in ImageParser.
