Comment 2 RHEL Program Management 2011-04-07 16:24:12 UTC 
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Comment 3 John Jarvis 2011-04-11 16:24:26 UTC 
IBM is signed up to test and provide feedback, setting OtherQA.

Add virtio disk identification support

Backport of the following patch:

commit 2930b313dd602d67a568815b0b031b824916cec9
Author: john cooper <john.cooper>
Date:   Fri Jul 2 13:44:25 2010 -0400

    Add virtio disk identification support

    This patch adds the final missing bits for support of
    passing a serial/id string to a virtio-blk guest driver.

    The guest-side component already exists in the virtio
    driver, and has recently been reworked by Ryan to export
    a /sys interface for retrieval of the id from guest userland.
