Resending to kvm mailing list, in case someone here might help... Also
will try again with newer ovmf, but assume it happens.

Temat: Windows 11 guest crashing supposedly in smm after some time of use

Hello.
I have windows11 installed on a vm. This vm generally works properly,
but then might crash unexpectedly at any point, this includes situation
like logging onto the system and leaving it intact for like an hour or
less. This can be reproduced by waiting long enough but there is no
single known action causing it.
What could be the problem?
Configuration and error details:
My host is a msi vector gp76 laptop with intel core i7 12700h, 32gb of
memory, host os is fedora linux 37 with custom compiled linux kernel
(fedora patches). Current kernel version is 6.1.10 but when I installed
the vm it was 6.0 or less, don't quite remember exactly, and this bug
was present. Not sure if bios is up to date, but microcode is, if that
matters.
Hardware virtualization enabled, nested virtualization enabled in module
params for kvm_intel.
For vm using libvirt, qemu 7.0.0. Virtual machine is q35, smm enabled,
processor model set to host, firmware is uefi with secureboot and
preenrolled keys, tpm is enabled. Most/all hyperv enlightenments are
enabled.
Using virtio for what I can including virtio-scsi, virtio-input,
virtio-net, virtio-balloon, etc... installed windows drivers for all of
these things.
Guest is windows 11 pro 64 bit.
What crashes is qemu itself, not that the guest is bsod'ing.
Below is the link containing libvirt qemu log, containing the full qemu
command line and also the crash messages. Note virtualization is
disabled in vm even though nested virtualization enabled on host, and
hyperv not installed on windows, so it's likely not the cause.
