[FAILURE] GPU/VGA Passthrough of NVidia GeForce GTX1650 to Windows 10 VM using Linux KVM on Ubuntu 18.04.3 LTS Desktop Edition PART 2

Sun Feb 2 01:15:33 UTC 2020

Resumed troubleshooting at around 12 noon Singapore Time on 2 Feb 2020
Sunday.

Upgraded motherboard BIOS to version F50 using Q-Flash.

Linux command: sudo ./windows10vm.sh

Output:

qemu-system-x86_64: -balloon none: warning: This option is deprecated. Use
'--device virtio-balloon' to enable the balloon device.
qemu-system-x86_64: -device vfio-pci,host=01:00.0,multifunction=on: vfio
error: 0000:01:00.0: group 0 is not viable
Please ensure all devices within the iommu_group are bound to their vfio
bus driver.

Conclusion:
Motherboard BIOS version F41 is still the best. BIOS versions F42h and F50
don't work at all.
With BIOS version F41, the IOMMU group is 7. Within IOMMU group 7, only
NVIDIA GTX1650 GPU exists.
With BIOS versions F42h and F50, the IOMMU group is 0 and there are too
many devices within this group (cannot work).

Using Linux kernel 5.5.1 encountered some problem.

Linux command: sudo ./windows10vm.sh

Output:

qemu-system-x86_64: -balloon none: warning: This option is deprecated. Use
'--device virtio-balloon' to enable the balloon device.
qemu-system-x86_64: -device vfio-pci,host=01:00.0,multifunction=on: vfio
error: 0000:01:00.0: failed to open /dev/vfio/7: No such file or directory

Any changes in /etc/modprobe.d require you to update the initramfs. Enter
at the command line:

Linux command: sudo update-initramfs -u

Linux command: sudo reboot

Linux command: sudo update-grub

Linux command: sudo reboot

Linux kernel 5.5.1 is still having some issues with loading vfio-pci kernel
module.

Falling back to Linux kernel 5.3.0.

Checked. Linux kernel 5.3.0 has no issues. Use Linux kernel 5.3.0 all the
way.

However, Windows 10 virtual machine still giving me BSOD with IRQL NOT LESS
OR EQUAL Stop Code.

2 Feb 2020 Sunday 5 PM Singapore Time: I am very lost. I don't know what to
do next. Some experts please help.

Thank you very much.
