I'd like to test a nvidia K1 with pci assignement by using the pci-stub module or the vfio module. I'm running an ubuntu raring as the host and a version 1.4.0 of qemu-system-x86 1.4.0.
I just tested with QEMU emulator version 1.5.50 that I compiled from git but I have the same issue. The kernel running on the host is a 3.8.0-23-generic that comes with ubuntu.
I also tried to reset the card before binding it but I got the same issue: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error). Unable to determine the device handle for GPU 0000:00:03.0: Unknown Error 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 Regards, Guillaume -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
