Xen users - Apr 2010 - Do we need ACPI/APIC/NUMA/Schedule in dom0 ?

Hello all,

My machine is a dual xeon x5520 server with NUMA support.

I have some question about xen dom0 kernel.
Since xen hypervisor has provided vcpu schedule,
do we need to compile the following feature in dom0 kernel?

   - Tickless System (Dynamic Ticks)
   - High Resolution Timer Support
   - AMD IOMMU support
   - SMT (Hyperthreading) scheduler support
   - Multi-core scheduler suppor
   - Numa Memory Allocation and Scheduler Support
   - ACPI (Advanced Configuration and Power Interface) Support

Because domU doesn''t have ACPI support, the others are not functional
in
domU.
But do we still need the following two item in domU kernel?

   - SMT (Hyperthreading) scheduler support
   - Multi-core scheduler suppor


Thanks.

Best regards,
Chao-Rui
