Dear list,

I've encountered the following problem. I have two disks:

  /var/lib/libvirt/images/fedora.qcow2  (which contains OS)
  /dev/sde (iSCSI dummy disk just for testing)

Now, when I configure QEMU to start with both of them, QEMU/Seabios
tries to boot from /dev/sde which fails obviously. Even setting
bootorder does not help. Here's my command line:

  qemu-system-x86_64 \
  -boot menu=on,strict=on \
  -device lsi,id=scsi0,bus=pci.0 \
file=/var/lib/libvirt/images/fedora.qcow2,format=qcow2,if=none,id=drive-scsi0 \
  -device scsi-hd,bus=scsi0.0,drive=drive-scsi0,bootindex=1 \
  -drive file=/dev/sde,format=raw,if=none,id=drive-scsi1 \
  -device scsi-block,bus=scsi0.0,drive=drive-scsi1,bootindex=2

It was found that if 'drive-scsi1' is scsi-hd instead of scsi-block
everything works as expected and I can boot my guest successfully.
