[pve-devel] qemu 1.0 : scsi boot not working anymore

Hi again,
I finally found the right way, we need to pass scsi bootindex to romfile.


 -option-rom 8xx_64.rom,bootindex=xxx

and don't touch on romfile of nics

bootindex on scsi disk not working (so we can boot only on the first scsi disk, because we can tell to lsi)

so:

if scsi disk in boot order
  if 8xx_64.rom exist
    add -option-rom 8xx_64.rom,bootindex=xxx
  else
    send warning to user to tell him to download an put the romfile in /usr/share/kvm

What do you think about it ?

because it try to boot from nic, and never go to lsi to boot. (don't ask me why, it must be a bug...) 

I have do more test, and I found a working method to have network boot try and after scsi boot: 


add romfile= to nics 

and 
-option-rom 8xx_64.rom -option-rom pxe-virtio.rom 

(replace pxe-virtio by nics models, nics roms are in /usr/share/kvm) 


then, with that syntax, it'll try to boot on pxe (always,bootindex is not use, and after scsi) 

what do you think about it ?

Wait - why remove remove romfile= from nics ?
