This only works for paravirt guests.

Not at all strange. HVM guests can't do controlled shutdown process unless
you install special Xen paravirt drivers inside the guest. Without those
drivers it will just hard poweroff. Since you've using Cent OS 5 as your
guest you really would do much better with paravirt instead of HVM - you'll
easily have x100 the network performance with paravirt for example

Only for paravirt unless you have extra drivers in the guest
