Running qemu-system-x86_64 -name manjaro -enable-kvm -cpu host -smp cores=4,threads=1 -M q35 -m 8G -cdrom /mnt/Storage/ISO/manjaro-gnome-20.0.3-minimal-200606-linux56.iso -machine type=pc,accel=kvm -vga virtio -display gtk,gl=on however, (difference being gtk instead of sdl), the screen is black, and the vm still starts.
