To be more specific

 'xend' use /var/lib/xend for storing master config files in SXPR format.
 'xm' abuses python as a config file format in /etc/xen. XenD itself has
 no knowledge of these files, so it can't manage them. They should not
 be used in Xen >= 3.0.4 If you have existing files in /etc/xen, then you
 can load them into XenD by doing 'xm new configname', at which point
 both Xend and libvirt will be able to manage them. For Xen < 3.0.4
 libvirt has some limited support for reading /etc/xen files directly
