Xen's reboot code is a dumb rip-off from Linux. Some of the parameters 
for choosing type of reboot are not 'wired up'. What's there now seems 
to work on the vast majority of systems. I don't understand how 
different reboot triggers in domain0 can have an effect on whether the 
system actually reboots or not. I believe the Xen reboot code is 
unaffected by guests.
