To explore kvm installs via Virt-Manager, I tried win7 installs in 3 different hosts. All 3 have 2G of RAM or more.

Windows 7 Ultimate in 2.5 GB DVD ISO

  1) Centos 5.4, AMD am2, Athlon 64 x2 4600+
     works 2nd attempt after setup of Br0 (bridged network)

  2) OpenSuSE 11.2, AMD am2, Athlon 64 x2 5200+
     works with defaults (Br0 is setup on OS install)
      virt-manager 0.8.0-5

  3) Centos 5.4, Intel LGA 775 C2D, E7600 3.0 Ghz
     fails in shelled kvm and Virt-Manager with Br0

the Intel C2D box works so well - cooler and faster then the other two - but somehow the kvm intel support seems flawed. The win7 install gets past 2 boots and issues a VM exception in vcpu0 right after the third boot.

Maybe someone else succeeded with a similar Intel setup.
