Summary: SMP 8-way guests fail to boot

Initial Comment:
Tried the recently added 8-way SMP on KVM-AMD. (Dual-CPU , Quad-Core AMD 
Barcelona K10)

Guests fail to boot.

Guests:
- Windows Server 2003 (32-bit)
- Windows Server 2008 (64-bit)
- Fedora 8 (64-bit)

Windows experience BSODs, while Linux just stucks during "init" phase.

While SMP 2 and 4-way are also were sometimes hanging, this one (8-way SMP 
hang) is consistent.

I have tried only KVM-AMD, because I don't have (yet) such an Intel machine.

Alexey,

Can you please provide more details on the problem? 

- kvm_stat --once output once the guest is hung
- is the qemu process consuming excessive CPU time on the host?
- on the Linux case, is it a hard hang or can you still see the 
guest accepting keyboard input?
