Unable to boot VM with scsi enabled.

[Maciej Józefczyk]

Hello,

my environment:
- qemu: 2.5+dfsg-5ubuntu10.13~cloud0
- seabios: latest master

I'm trying to boot VM with parameters:

<disk type='file' device='disk'>
      <driver name='qemu' type='qcow2' cache='none'/>
      <source file='/home/instances/xxxxx-xxxx/disk'/>
      <target dev='sda' bus='scsi'/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
<controller type='scsi' index='0'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04'
function='0x0'/>
</controller>

and it fails  with message (instance screen):
Booting from Hard Disk...
Boot failed: could not read the boot disk
No bootable device.

I figure out that rollback of those commits:
- 3198c06b7b5457eecf5fbc6fd47fbea300a843e7 (lsi-scsi: try to enumerate
luns with REPORT LUNS)
- 11277846e819b9eef3db5ac833a6a47f95f5ef15 (lsi-scsi: reset in case of a
serious problem)

Solves the problem. What i'm doing wrong? Maybe its a bug?

Thank you!

Maciej

Quite possible.

I reproduced it with QEMU from Fedora25 and I'm looking into it now.
