Hello everyone,
As many other before me, I'm having problems with GPU Passthrough. I'm
running Fedora 20 with kernel 3.13.3 and the packages from the virt-preview.
My configuration is a Dell OptiPlex 7010, equipped with a Core i5 3470 and a
Radeon HD7570 from Dell.
VT-d and vfio work fine for other devices, such as the audio controller, but I
can't seem to passthrough the graphic cards. Primary passthrough simply
fails, secondary passthrough with a Cirrus VGA gives me Error 10. In both
cases, I hear the GPU fan reacting when the VM boots, but then nothing happens.
I tried blacklisting completely the i915 driver, as I can live without it.
This is for a project aimed at a seamless interaction with a Windows VM, the
Linux hypervisor doing background processing, hidden from the user. Given my
situation, what are my best next shots ?
I'd recommend trying qemu.git as well, this stuff is still under active
development.
Also see this thread for some possibly related discussion:

But maybe Alex has more suggestions.
