Description Kirby Zhou 2011-04-20 06:35:06 UTC 
Description of problem:

Windows XP, Windows 7 and something else only support 2 socket smp.
If I run a RHEL6 host on a 2-way SMP machine with 4 cores per socket, and allocate 4 vcpu to the guest. The guest OS will thing it obtains an 4-way SMP system with 1 core per socket. So Windows 7 and XP can only takes 2 vcpu per guest. It is very poor.

VMWare provides a parameter named 'corespersocket', it can solve the problem above. See http://kb.vmware.com/kb/1010184 for more details.

Please provide something likge 'corespersocket' to help us.

This is already supported, try something like this in your domain xml:

  <vcpu>4</vcpu>
  <cpu>
    <topology sockets='2' cores='2' threads='1'/>
  </cpu>

If that doesn't work, re-open.
