Hi,
I would like to know if it was possible to use only one gpu for the
host and guest system.
For example, i use my Nvidia gpu to Linux to play at games, to watch
HD videos. And if i want to play on Windows, i do that :
1- close X with systemctl stop gdm3
2- Launch a script which unbind the nvidia driver from my device and
bind to vfio driver.
3- launch a script with the qemu command to launch the VM. In this
script there is the way to unbind vfio driver and bind nvidia driver
when the VM is close.
I found a script which allow to unbind nvidia driver and bind vfio
without reboot. lspci -nnk confirm that.
But when i launch the qemu's script, the gpu is correctly used by qemu
but i stil have a black screen. The host has a black screen too.
Thanks,
Maxime
