Description Sibiao Luo 2013-10-17 12:16:50 UTC 
Description of problem:
only LUN 0 is recognized by seabios for virtio-scsi device, seabios will fail to recognize virtio-scsi device if specify LUN not 0.

Version-Release number of selected component (if applicable):
host info:
# uname -r && rpm -q qemu-kvm && rpm -q seabios
2.6.32-422.el6.x86_64
qemu-kvm-0.12.1.2-2.414.el6.x86_64
seabios-0.6.1.2-28.el6.x86_64
guest info:
2.6.32-422.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.boot guest with virtio-scsi device specified LUN is not 0.
e.g.:...-drive file=/home/my-data-disk.qcow2,if=none,id=drive-data-disk1,format=qcow2,cache=none,werror=stop,rerror=stop -device virtio-scsi-pci,bus=pci.0,addr=0x7,id=scsi0 -device scsi-hd,drive=drive-data-disk1,id=data-disk1,bus=scsi0.0,lun=1 -drive file=/home/my-data-disk.raw,if=none,id=drive-data-disk2,format=raw,cache=none,werror=stop,rerror=stop -device virtio-scsi-pci,bus=pci.0,addr=0x8,id=scsi1 -device scsi-hd,drive=drive-data-disk2,id=data-disk2,bus=scsi1.0,lun=2
2.press F12 during POST.

Actual results:
after step 2, seabios fail to recognize virtio-scsi device if specify LUN not 0.
Press F12 for boot menu.

Select boot device:

1. Virtio disk PCI:0:4
2. Floppy [drive A]
3. DVD/CD [ata1-0: QEMU DVD-ROM ATAI-4 DVD/CD]
4. gPXE (PCI 00:05.0)
5. Legacy option rom

Expected results:
seabios should recognize virtio-scsi device if specify LUN not 0.
e.g:
1. Virtio disk PCI:0:4
 * Virtio-scsi Drive QEMU QEMU HARDDISK 0.12 *   <----------
 * Virtio-scsi Drive QEMU QEMU HARDDISK 0.12 *   <----------
2. Floppy [drive A]
3. DVD/CD [ata1-0: QEMU DVD-ROM ATAI-4 DVD/CD]
4. gPXE (PCI 00:05.0)
5. Legacy option rom

Yes, this is a known limitation that may be lifted later.
