Any idea what the problem is?

Did you set the CPU number to 2 after the installation of Windows Server? In this case it is possible that windows is not using the appropriate hal (appearantly it may use the single-processor one).
Imagine this as some kind of a different kernel: If you compile your Linux kernel without SMP/multi-cpu support you will only be able to use one core/cpu.

I forgot to activate IO APCI. After activated, i installed the virtual machine again and it works.
