Hello,There is a fbdev issue with the virtio-gpu-pci and virtio-vga. (The penguins are not displayed at boot time)
Error message: [ 0.889302] virtio-pci 0000:00:02.0: [drm] *ERROR* fbdev: Failed to setup generic emulation (ret=-2)
The kernel 6.6 final doesn't have this issue. Please check the fbdev changes in the drm updates 'drm-next-2023-10-31-1'. Thanks, Christian
