This is not using virtio-scsi. A virtio-scsi disk would appear as /devs/sda in the VM. For example: <disk type='block' device='lun'> <driver name='qemu' type='raw' cache='none'/> <source dev='/dev/mapper/360022a110000ecba5db427db00000023'/> <target dev='sdb' bus='scsi'/> <address type='drive' controller='0' bus='0'/> </disk> <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source dev='/dev/mapper/360022a110000ecba5db4074800000022'/> <target dev='sda' bus='scsi'/> <address type='drive' controller='0' bus='1'/> </disk> <controller type='scsi' index='0' model='virtio-scsi'/>You can now try sg_inq for both disks. One will show your NAS's product and vendor names, the other will show QEMU as vendor and QEMU HARD DISK as product.
