In order to force all DomUs to shutdown, instead of suspending, during Domain 0’s shutdown, all you have to do is make following changes in /etc/sysconfig/xendomains: Leave empty the XENDOMAINS_SAVE variable. By default, it uses /var/lib/xen/save as the directory where the states of the DomUs are saved. By leaving it empty, the states of the virtual machines are not saved, but they are shut down as usual.
