My system is a single Core Duo T2300.  I assumed Xen took
care of dual core scheduing, so I've been using original
XEN3_DOM0 and XEN3_DOMU without modification.  Should I
configure DOM0 to support SMP?

Anyway, Xen 3.1.0 is showing following.

(XEN) CPU: L1 I cache: 32K, L1 D cache: 32K
(XEN) CPU: L2 cache: 2048K
(XEN) CPU: Physical Processor ID: 0
(XEN) CPU: Processor Core ID: 0

(XEN) CPU: L1 I cache: 32K, L1 D cache: 32K
(XEN) CPU: L2 cache: 2048K
(XEN) CPU: Physical Processor ID: 0
(XEN) CPU: Processor Core ID: 1

Core Duo is using a single 2MB L2 cache from both core.  So,
it is possible to happen some issue here.  No issue before,
at least I didn't notice issues before, though.
