Dom0 too.  This is part of the work implementing what we discussed a 
while back - Xen now completely owns the local and IO apics, so dom0 
only deals with Xen, not the hardware.  Xen has a completely different 
interrupt setup path, but at least it isn't a mishmash of Xen stuff and 
native APIC stuff.
