[libvirt-users] Windows Guest ignores CPU topology settings on Ubuntu Lucid host

I try to assign 8 host cores to Windows 2003 Server Standard guest. 
Because this OS version has a limit of 4 sockets, I have to change the 
CPU topology. My guest definition:

   <vcpu>8</vcpu>
   <cpu match='minimum'>
     <model>core2duo</model>
     <topology sockets='4' cores='1' threads='2'/>
   </cpu>

doesn't work as expected. I should have 4 CPUs in the Device Manager and 
8 CPU charts in Task Manager, but I have the opposite. And no matter 
what numbers I set in the topology, the guest always detects 8 sockets. 
What am I doing wrong?

libvirt 0.7.5
qemu-kvm 0.12.3
