Alex, I try to get KVM with VGA passthrough working properly. I have i915
(HD 4600) on the host and GTX 580 for the guest. The guest GPU is not

patch for i915.enable_hd_vga

not send SIGBUS, but allocate memory.
I would suggest to consider to use some other interface for the

I've noticed message on kvm exit:
Warning: serial8250__exit failed.
