Hello,

So i started to get i blue screen on my machine after i shut down entirely my proxmox cpu, i switch cases to an open one, after that when i booted one of my VM i started to get a BSOD which says SYSTEM THREAT EXCEPTION NOT HANDLE, that VM has Win11, so i decided to delete the VM and recreate it from scrach, to my surprise i get the same blue screen just after pressing a key to boot into windows instalation, so idk whats going on, if anyone has experience this issue or have any idea how to fix it please toss me a sugestion.

I already tries changing cpu from host to various options, but all of them offer the same result, idk what could of happened, since everything was working fine before i shut down my proxmox cpu :-(

heres the conf of my VM

args: -cpu host,-hypervisor,kvm=off, -smbios type=0,vendor="American Megatrends Inc.",version="1.A2",date="11/16/2021"

So after some testing, found out that if i have the -hypervisor flag on the args line, i get the bsod, but if i remove it, then everything work fine, thing is if i remove it, then windows detects the machine as a virtual machine :-( what am i missing here?
 
Hey, this seemed to work for me https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Bluescreen_at_boot_since_Windows_10_1803 . I am a noob with this stuff too, so stumbling my way through this at the moment.
Well i format my computer and did a fresh install of proxmox, now its working back again, but if this happens again ill try ur method, i hate to not know how to fix things, good thing is with a quick backup of all my vms, everything was working again in less than 30 mins :)
