hi, all
in guest xp vm , device management shows a help sign on cpu device, it has two vcpu, only one is recognized(NODE has two physical cpu).
qemu is build by myself from souce code, qemu-1.5.0, centos 6.4
a picture is attached .
---libvirt--------------
<vcpu placement='static'>2</vcpu>
  <os>
    <type arch='x86_64' machine='pc-i440fx-1.5'>hvm</type>
    <boot dev='cdrom'/>
    <bootmenu enable='yes'/>
  </os>
  <features>
    <acpi/>

Hi,

from the topology-line I would assume, you should switch sockets=1 and 
cores=2, multiple sockets would mean multiple processors vs. one 
processor with multiple cores.

Hope it helps,

Oliver.
