I'm currently trying to get this working on Ubuntu 14.10 on kernel 3.19 and am having a lot of issues. When I try to boot it with qemu, a see a small black window pop up with:
and no output from the second monitor (my tv). I have also tried using Virtual Machine Manager, which, after passing through my GTX 760, gives me a virtual window on my main monitor. I installed windows 8.1 on it and saw that I had a code 43 on my GTX 760. I tried installing drivers for it on the guest machine (a few different releases back to 335.23) and none of them solved the issue.
Here's my execution script:
My output of dmesg | grep pci-stub:
The contents of /etc/modules:
The contents of /etc/default/grub:
I have tried the ACS and i915 patches, neither of which helped. However, I'm not entirely sure I did it right because I haven't found a clear quide on how to apply them. I tried it the way done in http://ubuntuforums.org/showthread.php?t=2262280 this guide.
My specs are:
Gigabyte H77 motherboard (with vt-d turned on)
NVIDIA GTX 560 for the host
EVGA GTX 760 for the guest
Intel i5 Quad Core
Would anybody care to help me out? :)
