[Kimchi-devel] [PATCH v3 1/4] CDROM Management: Add storage sub-collection to sub-resource to guest resource

[Daniel H Barboza]

UPDATE:

I've talked with Aline and she made a good case on why I should rip off 
the "hard disk" support from this patch. I wasn't aware that this 
support is a separated item assigned to someone else.

The version 4 of this contribution will have cdrom support only.
