After this patch, I cannot boot a guest at all:


qemu-system-ppc64: Incorrect order for descriptors


This is my cmdline (basically, virtio-scsi):

/home/aik/p/qemu/ppc64-softmmu/qemu-system-ppc64 -nodefaults -chardev
stdio,id=STDIO0,signal=off,mux=on -device
spapr-vty,id=svty0,chardev=STDIO0,reg=0x71000100 -mon
id=MON0,chardev=STDIO0,mode=readline -nographic -vga none -enable-kvm
-device virtio-scsi-pci,id=vscsi0 -drive
id=DRIVE0,if=none,file=img/u16_04_32G_htx_406.qcow2,format=qcow2 -device
scsi-disk,id=scsi-disk0,drive=DRIVE0 -bios ./slof.bin -machine pseries
