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?
