Didn't you know kernel build on DomU is faster than native?
I remember Fujitsu has post this kind of data, and I also got
this kind of data from Intel QA team.
I have suspected this data too.
After further thought, I think the main reason is
the services running on domU is less than those on native machine,
for example, all network-related services are not running on domU.
You can get this kind of data yourself. :-)
