Using NVIDIA Experience (this NVIDIA overlay that displays GPU temperature, load, and FPS) causes the virtual machine to crash after 10 minutes.

The VM restarts. A black screen appears, then it resets to the boot menu.

KVM managed via the Libvirt GUI. Linux is Ubuntu.

Every time I turn on the virtual machine, I have to remove and add the mouse, keyboard, and graphics card.

So, before turning on the virtual machine, I have to cliclk remove the mouse, keyboard, graphic cards and then click add .

Otherwise, after 15 minutes, the virtual machine resets (not a Windows BSOD, but a VM reset).

GPU Passthrough

The GPU has a separate IMMOU group, which only contains the GPU.

This happened on its own.
