As another poster already said...`man xm`.  Here's a hint: `/usr/sbin/xm
create ${config_file}`.  When you shutdown a guest it does leave the
list of running domains (i.e. what `xm list` shows you).  The default
location for VM configurations is '/etc/xen/'.  If you want them to
start at boot, sym-link the conf to '/etc/xen/auto/'.
