Public bug reported:

nova and horizon dashboard should support that specify the block devices(e.g. /dev/sd*) to attach to an instance. Users can type the block devices(e.g. /dev/sd*) to attach to the instance and the instance can map the block devices(e.g. /dev/sd*) with a symlink(e.g. /dev/sd* -> ../../xvd*), and the horizon dashboard can display this symlink relation to users.
e.g.:
Instance: /dev/sd* -> ../../xvd*
Dashboard: /dev/sd* ---- vol-xxxxxx ---- /dev/xvd*

While Amazon EC2 has supported this function very well.

In the EC2 Attach Volume dialog box, start typing the name or ID of the
instance to attach the volume to in the Instance box, and select it from
the list of suggestion options (only instances in the same Availability
Zone as the volume are displayed).

Device names like /dev/sdh and xvdh are used by Amazon EC2 to describe
block devices, the block device mapping is used by Amazon EC2 to specify
the block devices to attach to an EC2 instance.

Please refer to the following picture for detail.
