My host is Gentoo x64, kernel 3.5.2, qemu-kvm 1.1.1-r1, libvirt 0.9.13, seabios 1.7.0

i try to set the boot order with scsi cd-rom first, then scsi harddisk

but the virtual machine will always boot with first scsi device only (unit='0', the scsi harddisk)

is it a known problem?

my libvirt config:

have anyone tested the boot order of virtio-scsi devices?

<os>
    <type arch='x86_64' machine='pc-1.1'>hvm</type>
    <boot dev='cdrom'/>
    <boot dev='hd'/>
    <bootmenu enable='no'/>
  </os>


i try to set the boot order with scsi cd-rom first, then scsi harddisk

but the virtual machine will always boot with first scsi device only (unit='0', the scsi harddisk)

is it a known problem?

Use the bootindex property of <disk> instead.

i add boot order and the virtual machine still boot from hard disk instead of cd-rom

<disk type='file' device='disk'>
      <driver name='qemu' type='raw' cache='unsafe' io='native'/>
      <source file='/Linux.raw_image'/>
      <target dev='sda' bus='scsi'/>
      <boot order='2'/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>
    <disk type='file' device='cdrom'>
      <driver name='qemu' type='raw' cache='unsafe' io='native'/>
      <source file='/xubuntu-12.04-desktop-amd64.iso'/>
      <target dev='sdb' bus='scsi'/>
      <readonly/>
      <boot order='1'/>
      <address type='drive' controller='0' bus='0' target='0' unit='1'/>
    </disk>

Ah, ok.  libvirt for now supports only booting from LUN 0.  You can use
multiple targets instead of multiple units.

Please raise this issue on the libvirt lists, then.

actually, why is the problem related to libvirt, not qemu, nor seabios?

libvirt has generated the qemu command line with "bootindex" already.

-device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=2 -drive file=/xubuntu-12.04-desktop-amd64.iso,if=none,id=drive-scsi0-0-0-1,readonly=on,format=raw,cache=unsafe,aio=native -device
scsi-cd,bus=scsi0.0,channel=0,scsi-id=0,lun=1,drive=drive-scsi0-0-0-1,id=scsi0-0-0-1,bootindex=1

Oops, should have been SeaBIOS.

Yes, it's SeaBIOS.  It is documented in the code.
