How to prevent Microsoft Flight Simulator 2020 from bsod when started on a virtual Windows PC using KVM

I assume you already have a working virtual machine that uses pci passthrough and that it works just fine with other games.

BUT very time you start up MS Flight Simulator 2020 Windows crashes with a blue screen of death.
It took me some time to figure out, so I’m writing this in the hope that it saves some other poor souls time.

The fix is quite simple you need to give the option “ignore_msrs=1” to the kvm kernel module.
Create the file “/etc/modprobe.d/kvm.conf“
Containing the line “options kvm ignore_msrs=1“
And reboot the host.

See: https://wiki.archlinux.org/index.php/QEMU#Certain_Windows_games/applications_crashing/causing_a_bluescreen for a slightly more in depth explanation of this.
