Hi, Dan

Thank you for commenting.
Of course, I agree your point 
and that you are commiting it.

I am commenting it 
just because 2 month is not old ago in my feeling.


Here Is the memo for my understanding.
(Since I am not familiar with KVM)
2007/07/19 kvm-30 Guest SMP support
     (Parameter(KVM_MAX_VCPUS) changes from 1 to 4 in KVM-28)
2008/02/26 kvm-62 VCPUS changes 4 to 16

Thanks
Atsushi SAKAI
