I seemed to have fixed my vm reboots issue. Topton n5105 w/2usb 3 port, vga and hdmi.
Disable IME. Intel Management Engine
Limit C states to C3
Set P1 power limit to: 10000
Set P2 power limit to: 12000
Seems the CPU was spiking temps really high when I had P2 limit Set to 22000. I lowered it to 12000 and disabled IME as well as set limit to C states to C3.
Not sure which fixed it but I'm at 24 hours now and no VM lockups or mystery reboots. Will give it another day before I confirm this fixed issue. I did run a few stress-ng tests and so far so good.
