It seems like this series is now in qemu.git, but I still can't boot using -kernel.
I'm starting qemu as: /opt/qemu/bin/qemu-system-x86_64 \ -m 1500 -enable-kvm \ -kernel arch/x86/boot/bzImage \ -drive file=/dev/vg00/qemu-root,if=virtio,media=disk,cache=none,aio=threads \ -drive file=/dev/vg00/qemu-data,if=virtio,media=disk,cache=none,aio=threads \ -drive file=/root/test1.img,if=scsi,media=disk,cache=none \ -append "root=/dev/vda console=tty0 console=ttyS0,38400n8" and it simply hangs with a black screen once the SDL window opens
