I've gone through reinstalls and multiple guides (
http://vfio.blogspot.com/2015/05/vfio-gpu-how-to-series-part-3-host.html a
few times) and I'm not sure what to do next, no matter what I try I always
get the error code 43.
My setup. I have a "server" in my closet that has 2 nvidia cards in (a
GeForce GT 430 to run the system, a GeForce GTX 760 dedicated to the VM).
I've setup the GTX 760 to use the stub (see below). The processor I have is
a 'Intel(R) Xeon(R) CPU E5-2640 v2 @ 2.00GHz', so no integrated graphics on
that and the motherboard doesn't have any integrated graphics either. The
server runs Ubuntu Server 16.04.1, but has libvirt and qemu updated from a
PPA (see versions below). The VM is a Win 10 64-bit Home install with the
NVidia 375.70 drivers installed from their website.
I've verified that if I pull the GT 430 from the box that I can see the
boot on the GTX 760. If I leave both cards in, I don't see anything on the
GTX 760 ever. One thing to note is that I setup the VM using virt-manager
1.3.2 from a 16.10 machine, so in the XML it mentions
"machine='pc-i440fx-yakkety'".
I'm not sure if that could be causing any issues, but I've been working on
this for about a week and need a fresh set of eyes.
