Dom0 should be reserved only for management toolstack and minimal amount
of services (storage/network backends).

Actually dom0 is a *VM* aswell (see "xm list"), although it has more direct
access to the hardware and thus to storage. 

You're probably limited by the disk IOPS anyway, so it shouldn't
matter that much if you run the service in dom0 or in domU,
so go for domU, since that's the more safe bet.
