From: ChenHanxiao <chenhanxiao(a)cn.fujitsu.com&gt; If we add a virtio-disk, we need to add a SCSI controller with model 'virtio-scsi'. This patch allows libvirt to analyze disks XML with tag 'model': <disk type='block' device='disk'> <driver name='qemu' type='raw'/> <source dev='/dev/sdb'/> <target dev='sda' bus='scsi' model = 'virtio-scsi'/> </disk> If we got a disks XML with bus='scsi' model = 'virtio-scsi', we'll add a SCSI controller with model 'virtio-scsi' automatically.
