Is possible (any method) to switch between Graphics Cards while system is running? And than disabled card bind to KVM/QEMU?
I have a desktop.
I have 2 GPUs (1x Intel HD 4600 and 1x NVIDIA GeForce 1060)
I would like to have virtual Windows 7 using KVM with GPU passthrough.
Intel Graphics for Linux (host) NVIDIA for Windows 7 (guest)
I know that I have to set stub for NVIDIA.
I would like to have primary GPU Intel Graphics and use sometimes NVIDIA card using Bumblebee (nvidia optimus).
But problem is that then I can't bind NVIDIA card to virtual machine. Is possible to unbind drivers while system is running? I don't think it is problem, because X server is using primary iGPU (Intel Graphics, not NVIDIA)
