Unfortunately there is nothing under scsi:
[root at localhost ~]# ll /sys/class/scsi_*
/sys/class/scsi_device:
total 0
/sys/class/scsi_disk:
total 0
/sys/class/scsi_host:
total 0
I also tried kudzu (http://linux.die.net/man/8/kudzu), but it still
shows only the original drive:
[root at localhost ~]# kudzu
[root at localhost ~]# kudzu -p
...

class: HD
bus: VIRTIO
detached: 0
device: vda
driver: virtio_blk
desc: "Virtio Block Device"

While looking around I found this comment (in a bug not directly related):

Hot-add is not supported for RHEV 2.1.

So maybe it actually cannot work?
