No CPU in windows device manager, no MMX, 3DNow!, SSE, SSE2

Hello,

i'm using Kubuntu 7.10 as host system. My CPU is an AMD Athlon64 X2 4800+. My VirtualBox Verison is 1.5.2. I've installed a guest sytem with WindowsXP SP2. The guest additions are installed as well. In the windows device manager, i can't see any available processor. The task manager shows me only one cpu, not a dualcore.

Now, my problem is to compile Qt4.3.2. I use the vm as development system, with Qt4.3.2 and Visual Studio. When I try 'configure' before compiling Qt it shows me the following:

Code: Select all

QMAKESPEC..................win32-msvc (commandline)
Architecture..................windows
Maketool.......................nmake
Debug symbols..............yes
Accessibility support.......yes
STL support...................yes
Exception support...........yes
RTTI support..................yes
MMX support..................no
3DNOW support..............no
SSE support..................no
SSE2 support................no
OpenGL support.............yes
Direct3D support............no
OpenSSL support...........no
QDBus support..............no
Qt3 compatibility............yes

With vmware guest or natively on my host, I don't have any problems with CPU support (MMX, 3DNow!, SSE, SSE2). Can anyone help me?
