Heiko Sieger's blog: Running Windows 10 on Linux using KVM with VGA Passthrough

Link: https://heiko-sieger.info/running-windows-10-on-linux-using-kvm-with-vga-passthrough/

=======================================================================================================================================

I am following Heiko Sieger's guide because I think it is very well written and very well explained. Good job!

I need to come up with this guide for myself because the home desktop computer which I have is specific and unique to me.

Turritopsis Dohrnii Teo En Ming's home desktop computer technical specifications:

[1] Processor: AMD Ryzen 3 3200G with Radeon Vega 8 Graphics, 4 Cores, 4 Threads, 4.0 GHz Max Boost, 3.6 GHz Base
[2] Motherboard: Gigabyte B450M DS3H rev 1.0 Socket AM4 (BIOS Version: F41, BIOS Date: 07/22/2019, BIOS ID: 8A16BG05)
[3] Memory: 8 GB Transcend DDR4-2666
[4] Integrated Graphics Device (IGD): AMD Radeon Vega 8 Graphics (for Linux host)
[5] Discrete GPU on PCIe Slot 1: MSI GeForce GTX1650 Ventus XS OC Edition 4 GB GDDR5 (for Windows 10 version 1909 virtual machine)
[6] Solid State Disk (SSD): 256 GB Transcend SSD (bare-metal Windows 10 version 1909 installation)
[7] Harddisk (HDD): Seagate Barracude 1 TB 3.5" Internal SATA (for installing Ubuntu 18.04.3 LTS Desktop host)

I will configure bridge networking much later, after GPU Passthrough is successful. GPU Passthrough is top priority. I must get it to work first.

ERROR: Windows 10 virtual machine keeps showing BSOD with IRQL NOT LESS OR EQUAL Stop Code.
By the way, I am able to see the Tiano Core screen.
No matter what variables I play with in the shell script to start Windows 10 VM,
I always get BSOD IRQL NOT LESS OR EQUAL Stop Code. I am running out of options already.
Please give me suggestions.

Questions
=========

[1] Is MSI GeForce GTX1650 4 GB GDDR5 GPU not supported by Linux KVM for GPU Passthrough?

[2] Do I need to upgrade the BIOS of my Gigabyte B450M DS3H Socket AM4 motherboard? I fear bricking my motherboard. It is a risky operation.

[3] Are there any other workarounds that I have to do for AMD Ryzen 3000 series platform, in order to get GPU Passthrough to work?

I am looking forward to your replies.

Thank you very much!

Stopped troubleshooting at 5.19 AM Singapore Time on 2 Feb 2020 Sunday and went to sleep.

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

Upgraded motherboard BIOS to version F50 using Q-Flash.

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.
