Product: Base System
Version: 15.0-RELEASE

Severity: Affects Only Me

This only happens with Windows 10 and 11 guests. I don't have any logs because
of the hard reset.
The crash mostly occurs when Windows updates and restarts. The system (host)
freezes for a short time, then performs a hard reset.
I changed the disk_type from nvme to virtio-blk but exactly the same problem,
changed wired_memory="yes" to "no" same problem, happens with windows guest who
have passthru but also without.
That never happens with Linux or BSD Guest even if they have a much higher load
SSD and CPU wise.
