Debian :: Virtualize Win7 As Host On W520

My current situations is this:

I got an W520 with an i7-2720QM and Nvidia Quadro 1000m. I want to virtualize with Debian as host and Windows as guest. Therefore i want to assign my Nvidia GPU to the guest.

The reason for this choice is because I'm an mechanical engineering student, and that requires alot of windows-only programs (CAD/FEM/matlab etc)..

I got stuck at Nvidias error 43 problem.

Current situation:

I know all my hardware supports VT-d and is activated.
I got the intel-iommu=on as a boot parameter in grub.cfg.
I have stubbed and blacklisted my Quadro gpu so the Win7 guest can acces and use it.

I got win7 installed and running, it detects and refuses the quadro card because its virtualized. I have tried used the 377.88 Driver and the newest, with and without kvm as hidden. I have deleted all hypervisor tags.. It still reports error 43 ..

This is my config file over my virtual windows machine:

Code: Select all<domain type='kvm'>
  <name>win7</name>
  <uuid>5ebc2f74-7bbd-482d-99f4-660155187f8d</uuid>
  <memory unit='KiB'>6291456</memory>
  <currentMemory unit='KiB'>6291456</currentMemory>
  <vcpu placement='static'>4</vcpu>

[Code] ....

Do I use Xen insted?
