[Swlug] kvm question

[bascule]

i'm trying to turn off hyperthreading on my i7 4core to see what happens in my 
win10 kvm machine.

i turned it off in my uefi, mageia6 boots fine, i edited my win10 domain xml 
from:

<vcpu placement='static'>4</vcpu>
  <cputune>
    <vcpupin vcpu='0' cpuset='1'/>
    <vcpupin vcpu='1' cpuset='5'/>
    <vcpupin vcpu='2' cpuset='2'/>
    <vcpupin vcpu='3' cpuset='6'/>
    <emulatorpin cpuset='0,4'/>


to: 

<vcpu placement='static'>2</vcpu>
  <cputune>
    <vcpupin vcpu='0' cpuset='0'/>
    <vcpupin vcpu='1' cpuset='1'/>
    <emulatorpin cpuset='3'/>


but now my win10 machine won't boot, i still want to assign 2 whole cores to 
the win10 machine but without the hyperthreading.

any ideas?
