So I've been attempting to follow Tpc 010's tutorial on passing through a gpu to a windows 7 virtual machine. I'm on Devian 8.2, using the ovmf packages from sid. I' m using the integrated graphics on my i7 4790k for debian, and a gtx 970 for my windows 7 kvm.
Whenever I run the script shown below, it posts and then boots into the UEFI interactive shell. I'm assuming there is an issue within the script, but I cant seem to find it. By the way, I am getting video output from the monitor attached to the gtx 970.

-smp 4,sockets=1,cores=4,threads=2 \And this is hopefully correct for a gtx 970?
