I'm trying this on Proxmox VE, which is Debian 8 based.
I'm awaiting a UEFI bios from EVGA, but for now I don't have it available.
I'm following the "tips and tricks" series, but we differ at part 4, as I'd
like this to eventually work with my distro's web frontend.
With the goal of finding an invocation of the KVM command that will work, I did
a ps ax|grep kvm and modified what wasn't working in my distro to come up with
something that I think should work, which is:
=================

=================
Specifically, I added the ,kvm=off,hv_vendor_id=Nvidia43FIX and removed all of
the hypervisor hv_ stuff which might flag the nvidia driver.
My understanding is that I'm still running up against the "problem" of the
nvidia driver detecting that it is in a VM, and going into stupid mode.
I did take a shortcut in that I don't load the vfio module in the initrd, but
instead I assign driver overrides to GPUs respectively for both the nouveau and
vfio-pci, with a slightly modified version of the script from the howto series.
I don't think it's causing a problem in my setup, but I realize it isn't
ideal.. Nouveau seems to work well on the boot GPU, though I haven't tested it
much.
Here is some additional info which may be helpful:
