Oh boy here we go again !!!
Hello all,
Same as : here but this time the VM is a Linux (GPU is Nvidia)
GPU passthrough was working in 6.1 but not anymore in 6.2. I'm greeted with the error message "device does not support requested feature x-vga ".
And I can't boot without the x-vga otherwise inside the VM I can't use the GPU, nvidia-smi returns "Unable to determine the device handle for GPU ... : Unkown error"
Some logs/ouputs:
And the full error output I'm greeted with.
So goal is to understand what has changed between 6.1 and 6.2 and update the conf accordingly to make it work.
If anyone has any idea !
