I just tested with QEMU emulator version 1.5.50 that I compiled from=20
git but I have the same issue. The kernel running on the host is a=20
3.8.0-23-generic that comes with ubuntu.

I also tried to reset the card before binding it but I got the same iss=
ue:

  NVIDIA: could not open the device file /dev/nvidia0 (Input/output err=
or).
  Unable to determine the device handle for GPU 0000:00:03.0: Unknown E=
rror

even if in /dev I have:

  $ ls -l /dev/nvidia*
  crw-rw-rw- 1 root root 195,   0 juil.  9 12:09 /dev/nvidia0
  crw-rw-rw- 1 root root 195, 255 juil.  9 12:09 /dev/nvidiactl
