Only LUN 0 is supported for booting in current seabios.

src/virtio-scsi.c
static int
virtio_scsi_scan_target(struct pci_device *pci, u16 ioaddr,
                        struct vring_virtqueue *vq, u16 target)
{
    /* TODO: send REPORT LUNS.  For now, only LUN 0 is recognized.  */
    int ret = virtio_scsi_add_lun(pci, ioaddr, vq, target, 0);
    return ret < 0 ? 0 : 1;
}
Comment 4 Asias He 2013-09-06 19:15:20 EDT
Are you booting from a scsi lun or ide disk? 

You have this in your cmd line.
-device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,bootindex=0

Hi Asias,

we have below cmdline:

  -drive file='/root/test/autotest/client/tests/virt/shared/data/images/RHEL-Server-7.0-64.qcow2',if=none,id=drive-ide0-0-0,media=disk,cache=unsafe,snapshot=off,format=qcow2,aio=native \
    -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,bootindex=0 \

bootindex of this IDE drive is 0, so I thinks guest should boot from this drive first but in fact guest fail to boot at init scsi disk in seabios, you can check seabios for details;

Thanks,
Xu
Comment 7 Paolo Bonzini 2014-01-13 09:20:16 EST
It will eventually boot, but each target will make the scan take 5 seconds.  Example (15 seconds):

/usr/libexec/qemu-kvm ~/test2.img -m 384 \
    -debugcon stdio -global isa-debugcon.iobase=0x402 -m 384
    -device virtio-scsi-pci \
    -drive if=none,id=cd0 -device scsi-cd,scsi-id=0,lun=2,drive=cd0 \
    -drive if=none,id=cd1 -device scsi-cd,scsi-id=1,lun=2,drive=cd1 \
    -drive if=none,id=cd2 -device scsi-cd,scsi-id=2,lun=2,drive=cd2

The easiest fix is to support TEST UNIT READY in the QEMU TARGET device, so I'm changing the component.
