Summary: AMD CPU + KVM BUG.. Can't Share CPU..

Initial Comment:
* CPU(2EA) : Quad-Core AMD Opteron(tm) Processo

* TEST KVM-VERSION : KVM-63,68,69

* Total Memory : 16GB

* MainMoard : TYAN S2933


<Problem>
######################################################
This System's Total CPU is.. 8EA...
CPU#00, CPU#01, CPU#02, ...... CPU#06, CPU#07

If Running GuestOS's Numbers be more than physical
CPUs Number(8).. then, All GuestOS is Crashed....
and QEMU Process's CPU Usage is 100%...
######################################################


Example..
======================================================
1) total core is 8 (AMD CPU : kvm-amd Module)
2) Run 8EA Guest-OS... No Problem...
3) Additionally.. Run Guest-OS.. Over 8EA..
   Then... All... or Some os Guest-OS is Crashed.. !!!
   and QEMU process;s CPU Usage 100% on 'top'
4) the other side, INTEL CPU (kcm-intel Moduel)...
   No Problem....
======================================================

* I guess...., this problem is kvm bug that can't share
physical CPUs...

* Attatched Jpeg File is... Crashed Geust-OS's VNC ScreenShot. 

* Please.. Check.. This Problem....
