Guests may start in the order that you specified, but there is no
guarantee that the database service on 000-database would be started
before the web service on 100-webserver and the loadbalancer service on
200-loadbalancer after the webservice on 10-webservice. Xendomain
service just starts guests in the order specified and guests are started
in the background, so time of the start up of services in the guest may
vary.

You may try adjusting the value of "XENDOMAINS_CREATE_USLEEP" in
/etc/sysconfig/xendomains to a sensible value to get the result that you
expected. Probably 3 minutes or 4 minutes.
