This is a new feature of Xen since 3.0.4 - the config files for guests are
managed directly by XenD itself, so are no longer kept in /etc/xen .

If you want a command line tool for managing guests, then virt-install can
provision new guests, and  virsh can be used to manage existing guests.

To edit the config of an existing guest, try something like

   virsh dumpxml  [guest name or id] >  config.xml
   vi  config.xml
   virsh define  config.xml

What you're doing here is requesting a dump of the XML doc describing the
guest, then editting it to suit your needs, and finally reloading the XML
config into XenD.  There's some docs on the format 
http://libvirt.org/format.html
For simple operations like changing memory settings and VCPU counts you can
also just use the approrpriate virsh command directly.  We're also working
on more virsh commands to allow addition & removal of network & disk devices
without needing to edit XML.

Dan.
