The struggles I faced getting Nouveau + VFIO to work
So, as mentioned in my previous post about VFIO, I’m running nouveau inside of a Linux VM using PCI passthrough. Here are some random tips and notes that I’ve learned. (Kernel: 4.10-rc8) The system shows “no signal” during modesetting. Workaround: Use nomodeset nouveau.modeset=0 kernel parameters to disable kernel modesetting. This, however, disables the nouveau driver, so you won’t be running any graphical applications. Solution: Use nouveau.config=NvForcePost=1 to force a POST on the graphics card.
