Created attachment 499640 [details] Add virtio disk identification support ------- Comment on attachment From strosake.com 2011-05-18 12:45 EDT------- 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.
