Host crash when playing specific game on guest Windows (Dark Souls ||)

Support Virtualization
1

As the title says, host os (Manajro) crashes (system reboots) when i play this one specific game. I just finished playing Dark Souls Remastered, i have played it for the past 2-3 weeks, not a single crash/issue. After few minutes of running DS II, PC reboots (host)

The setup is the following:
I have created Windows VM using libvirt (Virtual Machine Manager) with GPU passtrough. I am using Nvidia GameStream to stream games to my Nvidia Shield TV

I dont even know where to begin to debug this, can someone help?

Here is the log from journalctl (crashed twice, this is log after second reboot):

This looks interesting, from the log

The solution was to shut down completely, then turn back on again. Reboot didnt work, weird…
