I'm not following Xen as close as I'd like to, and as such your posting 
raised two questions for me that I was able to google. Maybe you can 
confirm my understanding:

1) HVM = Hardware Virtual Machine, a Common Interface for VT-x/VT-i and
         AMD SVM CPUs[1]

2) Qemu-dm = Qemu[2] Device Model - a modified(?) Qemu that's used to
             emulate instruction sets for real-mode support[3] - I guess
             to run Xen inside Xen
