Xen uses *two* native configuration file formats: S-expressions and a
Python-like syntax. The .sxp files you found below /var/lib/xend/ use
the former syntax, the guest configuration in /etc/xen the latter.
I'd recommend to stick to libvirt as much as possible. Check "man
virsh", in particular the domain commands "dumpxml" and "define".
