Description of problem:
The behavior when converting an image to block device has changed and now fails with "qemu-img: Protocol driver 'host_device' does not support image creation"

[root@lynx23 ~]# lvcreate -L 100M f1373d19-38a2-4730-b092-3a86b7f3b22d -n foo1
  Rounding up size to full physical extent 128.00 MiB

qemu-img: Protocol driver 'host_device' does not support image creation

This can be fixed by adding the '-n' flag, but breaks current behaviour
