I don't have any logs beca= use 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 proble= m, changed wired_memory=3D"yes" to "no" same problem, happens with windows gue= st 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
