[Xen-users] cpuid configuration for 2X quad core xeon with ht

[Hinrich Aue <Hinrich.Aue@xxxxxxxxx>]

Hello list,

we are trying to get a windows 2003 enterprise running with our 2 socket xeon 
quad core with hyperthreading.

Since xen turns every thread into a cpu, we could not use enterprise, it only 
supports 8 CPU, but we want the hyperthreading as well (16 logical cpu).

We tried
cpuid = 
['1:edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx,ebx=xxxxxxxx00001000xxxxxxxxxxxxxxxx','4,0:eax=001111xxxxxxxxxxxxxxxxxxxxxxxxxx']
vcpus=16

but windows does not start with it.
When we set vcpus=8 then it starts - with 8 cpus of course.

Does anybody have an idea for the correct configuration?

Thanks,
        Hinrich
