I don't think there's a way to step into virt-manager's process of
defining domains. However, you can use virt-install directly instead. It
can just print the XML instead of defining it in libvirt. You can take
this document, modify it and then 'virsh define ...' it.

What you are seeing is a bug that is fixed already.

Also I should point out that libvirt-2.0.0 is two years old release.
Nearly. Upgrade if you can.
