My operating System is Debian Lenny AMD64 running on an AMD Athlon II X4 605e with 8GB memory. The Guest has the AMD CPU driver installed.

Any idea what the problem is?

With what did you determine it only sees one core?

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.
