[Solved] KVM causes kernel panic

Munsio · 27 January 2021 08:05

Hi,

I have problems with a freezing Win10 VM and kernel panics which sometimes result that the freezing VM is taking the host with it which only a reboot can resolve.

What I do:
I am using a Windows 10 VM and PCI passthrough for gaming.

System:
Ryzen 5 3600X
Gigabyte X570 AORUS ELITE - Bios Version F31 - 31.12.2020 d.m.Y
4x 8GB G.Skill Ripjaws 3600 C16 - In XMP profile 1
MSI GeForce RTX 2080 SUPER GAMING X TRIO - pci passthrough to guest
MSI GeForce GT 1030 - host
SupaGeek 5-Port-PCI USB-3 Card - passthrough to guest
Samsung SSD 970 EVO - 500GB
Samsung SSD 860 EVO - 1TB

Disk partitions
860 EVO - NTFs drive for the VM where all the games are on
970 EVO

512M UEFI Boot partition
390GB luks partition - Manjaro
75GB ntfs - Windows

Versions:

Qemu - 5.2.0
Virsh - 6.5.0
Kernel - 5.10.7-3-MANJARO / 5.11.rc3-Manjaro
VFIO-Guest - 0.1.190-1
Windows 10 - 19042.746
Win10 Nvidia driver - 460.89

What I also observed is that those panics are total random. Sometimes the VM runs 4-5mins until it freezes, yesterday I got >1H runtime without problems.

Sometimes there isn’t even any panic or output on dmesg or journalctl but the VM freezes complete (including those nasty sound buffer lock sounds)

I hope that I am in the right place here, if not it would be great if you can provide a direction where I should post this problem.
