check cron jobs on your host. cron job should check
rebooted VEs every minute and start them back.
Probably you have not waited for a minute :)

`service vz stop` does stop VEs first. So if you did a gracefull node reboot
VEs should have stopped automatically (service vz is stopped on node shutdown).
Sure, apps should be stopped first for gracefull applications shutdown.
Otherwise some applications can be disappointed by broken/not-closed data files.
