I spent a frustrating week trying to get this to work so I hope this thread will help other people out. I kept getting stuck at "code 43" in windows after installing the nvidia driver. Turns out I had the wrong version of qemu and didn't use the kvm=off feature, which is the key to passing this card through correctly.
Here are my machine's specs
ASUS Sabertooth 990fx rev2
AMD FX8350
ATI Radeon HD 6450 (Host's Card)
EVGA Nvidia GTX 560 Ti (Windows 7 guest Card)
I used qemu-system-x86_64 version 2.1.2. It allows you to use kvm=off. You can get it by using the Serge Hallyn repo here:
I had some problems getting the seabios to work right after I upgraded qemu, due to a symlink missing, so do this:
You're going to need kvm installed using this tutorial:
https://help.ubuntu.com/community/KVM/Installation
You're also going to need to download the 3.18.0 kernel from here:
https://www.kernel.org/pub/linux/ker...ux-3.18.tar.xz
You're going to need the ACS and i915 patches from here:
https://docs.google.com/file/d/0Bxp_...E5NE9mOUk/edit
Just click the download button at the top of the page.
Extract the linux-3.18.tar.gz file, I used archive manager to do this. Then move the files from the linux-mainline folder, containing the patches, into the linux-3.18 folder you just extracted. I'm no compiling expert, but this is what I did:
After that just make menuconfig or however you want to configure your kernel and then compile. Don't forget to enable all of the KVM, VFIO, and virtualization things. If you don't know how to do this, there are hundreds of tutorials on the webs.
Reboot into the new kernel.
Here is the rest of the info you need. Remember this is for an AMD processor. If you have an intel processor, you'll have to change the relevant items. Important stuff in bold.
/etc/default/grub
lspci -nn | grep NVIDIA
/etc/modules
/etc/initramfs-tools/modules
/etc/vfio-pci1.cfg
reboot your computer
Check to make sure the card got stubbed at boot by using
You should see your cards ID followed by "claimed by stub" I stubbed both the graphics and the sound on the card.
Now for the Guest's startup script. I had to patch mine together using like 4 different startup scripts I saw on different forums, youtube, ect.
I have an extra keyboard, mouse, and usb audio device hooked up to my computer just for this and here's my lsusb output, just so you can see how I got the ID's for passing the usb to the guest.
/usr/Windows
To make this script executable run
Make sure you have a monitor attached to your nvidia card and startup with:
Good luck, I hope this helps people where I got stuck. The kvm=off feature only works in qemu 2.1.2.
