  If the config files are installed in /etc/xen/ and assuming they
use only declaration and no other Python code, then libvirt if compiled
with xen support will look at them as definitions for domains. That
way you can just use for example 'virsh dumpxml' to get the associated
XML for the defined domain. Basically at the API level you do a domain
lookup based on the name (virDomainLookupByName) or UUID, and then 
call virDomainGetXMLDesc() on the result. Those calls are available at the
python binding.
  But there is no direct API to convert Xen config files to the XML,
and Xen config files being python code actually this didn't made 
sense to try to expose it at the API level which is defined in C. The
definitions really use XML as the format for libvirt, and as much
as possible they are not tied to the specifics of a given hypervisor.
